A chemical element is a form of matter that cant be broken into smaller pieces by any chemical reaction. Essentially, this means elements are like different building blocks used to construct matter.Ã At present, every element in theÃ periodic tableÃ has been discovered or createdÃ in a lab. There are 118 known elements. If another element, with a higher atomic number (more protons) is discovered, another row will need to be added to the periodic table. Elements and Atoms A sample of a pure element consists of one type of atom, which means each atom contains the same number of protons as every other atom in the specimen. The number of electrons in each atom can vary (different ions), as can the number of neutrons (different isotopes). Two samples of the exact same element may look completely different and exhibit different chemical and physical properties. This is because the atoms of the element can bond and stack in multiple ways, forming what are called allotropes of an element. Two examples of allotropes of carbon are diamond and graphite. The Heaviest Element The heaviest element, in terms of mass per atom, is element 118. However, the heaviest element in terms of density is either osmium (theoreticallyÃ 22.61 g/cm3) or iridium (theoreticallyÃ 22.65 g/cm3). Under experimental conditions, osmium is almost always more dense than iridium, but the values are so close and dependent on so many factors, it really makes no difference. Both osmium and iridium are about two times heavier than lead! The Most Abundant Elements The most abundant element in the universe is hydrogen, accounting for about 3/4 of the ordinary matter scientists have observed. The most abundant element in the human body is oxygen, in terms of mass, or hydrogen, in terms of atoms of an element present in the highest quantity. The Most Electronegative Element Fluorine is best at attracting an electron to form a chemical bond, so it readily forms compounds and participates in chemical reactions. This makes it the most electronegative element.Ã At the opposite end of the scale is the most electropositive element, which is the one with the lowest electronegativity. This is the element francium, which does not attract bonding electrons. Like fluorine, the element is extremely reactive, too, because compounds most readily form between atoms that have different electronegativity values. The Most Expensive Elements Its difficult to name the most expensive element because any of the elements from francium and higher atomic number (the transuranium elements) decay so quickly they cant be collected to be sold. These elements are unimaginably expensive because they are produced in a nuclear laboratory or reactor. The most expensive natural element you could actually buy would probably be lutetium, which would runÃ around $10,000 for 100 grams. Conductive and Radioactive Elements Conductive elements transfer heat and electricity. Most metals are excellent conductors, however, the most conductive metals are silver, followed by copper and gold. Radioactive elementsÃ release energy and particles via radioactive decay. Its hard to say which element is the most radioactive, as all elements higher than atomic number 84 are unstable. The highest measured radioactivity comes from the element polonium. Just one milligram of polonium emits as many alpha particles as 5 grams of radium, another highly radioactive element. Metallic Elements The most metallic element is the one which displays traits of metals to the highest extent. These include the ability to be reduced in a chemical reaction, the capacity to form chlorides and oxides, and the ability to displace hydrogen from dilute acids. Francium is technically the most metallic element, but since there are only a few atoms of it on Earth at any given time, cesium deserves the title.

Sample details Pages: 4 Words: 1268 Downloads: 9 Date added: 2019/03/22 Category Politics Essay Level High school Topics: Barack Obama Essay Donald Trump Essay Did you like this example? Should Americans have to pay for health insurance? If you are a young adult in todays day and age the first thought that would come to mind would be to say yes. By saying yes you are standing for the Affordable Care Act aka, Obamacare; which includes a requirement called the individual mandate. This is the mandatory health insurance of any and everyone who can afford to pay for it, thus creating money for the ones who can not. By saying no, you are agreeing that healthcare should be individual and that everyone should be held accountable for their own health and health care methods. These two concepts have been widely controversial for the past couple of years, with people disputing which is more unconstitutional than the other. The fact of the matter is that while the ACA may be socially and morally correct to most, it is much more unconstitutional, to say the least. THE AHCA IS SOMETHING THAT CAN CORRECT THE UNCONSTITUTIONAL NATURE OF THE ACA AND CAN HELP BRING JUSTICE, ACTION, AND CHANGE TO TODAYS MEDICAL CRISIS. When the American people think of their own laws and rights, one of the biggest ones is our freedom of choice. If it wasnt for this crucial concept in our society, America as a whole would not be the same, so why is it mandatory to pay for anything, let alone something as expensive as health insurance? DonÃ¢â¬â¢t waste time! Our writers will create an original "Obamacare vs. Trumpcare" essay for you Create order Health insurance has always been expensive but because of the requirements in which the ACA demands, insurance is now higher than ever. For the people who decide to opt-out, a penalty fee is given in order to force people to consider getting insurance and to provide insurance coverage for the ones who can not afford it. This is unconstitutional as people are getting a penalty for making more than what is considered enough in the eyes of the law. It also forces people to provide care for people they are not legally obligated to so, in the eyes of the law, this should be deemed wrong while in the eyes of society it can be deemed ethical. This penalty threat in turn ended up backfiring as many people decided to pay the fee instead of getting the actual insurance itself (Potter). 4 million people did this to escape the heavier prices that many insurance companies expect today (Amadeo). This shows that the American people do not see this as something that is just and should be paid for an d would rather go without insurance. Going without insurance is a risk they understand as their own and are held responsible for any payments they may need to make in order to get health care. Listening to our people should be the number one concern and many of them have shown that paying for others insurance is not something they want to be a part of. The law causes many issues, especially for the middle class. The prices alone are enough to heavily affect the lives and spending habits of many American citizens. It is estimated that 3-5 million people lost their health insurance due to it not complying to the Obamacare requirements (Amadeo). This left 3-5 million people lost and on a search to find another provider. This was another reason many people decided to pay the extra fee instead of going through the difficult process to find another insurance company which could, in turn, end up being much more expensive to fit all of the requirements and services that needed to be added to fit the new Obamacare standard. To fund this new plan, the taxes paid for by higher income families, middle-class families, and the health industry rose and created more of a stretch for cash for the middle-class families. Since they make up much of American citizens the economy is struggling to keep up. It also created a rise in health care prices short term due to all of the new parts to the coverage and the increased usage of these services. The ACA has the ability to ruin the economy and can be the difference between adding millions of more dollars to our debt or finally demanding individual responsibility. This is what the AHCA is about as it teaches people to provide for themselves rather than rely on a country that is already trillions of dollars in debt. There are many concerns regarding the AHCA and what it truly entails. Many fear they will lose their health care or will not qualify to receive it. While this is an understandable fear for many, it is not exactly reasonable. AHCA is a law that is very similar to ACA. It still works to provide people with quality health care and insurance but simply thinks that not everyone needs to participate. AHCA still uses many of the positive provisions that were provided through Obamacare, such as the non-discrimination of people with pre-existing conditions applying for insurance (Athar). This is something that was a big concern for many as they did not want to be turned away from insurance companies. The fear for many that are against AHCA is the quantity of health care providers that are available to help more people, what they are not looking at however is the quality of healthcare and how it is diminishing under Obamacare (Sataline). The quality of healthcare is slowly dwindling under the ACA, this is because there is a shortage of doctors willing to work under such conditions. It is estimated that the nation could be facing a shortage of up to 150,000 doctors in the upcoming 15 years, which will, in turn, cause a higher demand for doctors and prices will, again, start to rise. There is also a fear that because there will be such a shortage, that many patients will be turned away to focus on the more serious cases presented (Cusack). This is a problem as it can actually mean that fewer people are being provided with adequate health care and more people will have to find alternative methods of care. Since more people have access to health insurance using the ACA, the misuse of it will also increase creating crowding in ERs, hospitals, and clinics which will further the diminishing quality of healthcare under Obamacare. In conclusion, the ACA provides many with health care and insurance that they may not have been able to receive before. However, this is at the expense of the millions of middle and higher income families and individuals who must pay extra to support the ones who can not support themselves. This causes confusion within the different groups about who should pay what and how much. The ACA has been shown to be unconstitutional due to its lack of regard for the peoples freedom of choice, the strain it puts on huge groups in society, and lack of effectiveness it is having for most Americans. Their efforts to get people to involve themselves in obtaining health insurance have been unsuccessful with many people finding ways around the bigger payments that must be made to the insurance companies. It is also hard on the companies as they are being forced to create plans that suit the Obamacare requirements and many are shutting things down completely. While this plan works in theory, in real life many people are not so care-free with their money and work hard to obtain it in order to pay for the things that they want or need. Regulating what we pay for is going against our basic rights and our freedom of choice and because of that, it is unconstitutional in nature.

The study of the early years of the America republic has not received the same attention from historians, as have many other periods of American history. In fact, only slavery and sectionalism, the leading causes of the American Civil War, have been consistently covered in much of the historical study of the first half of the nineteenth century. This became quite obvious with the readings that I spent time with this semester. Many were somewhat long in the tooth, yet still remained standard bearers for their topic, as further study has been sporadic or nearly nonexistent. This seems especially true of the studies that attempt to bring together the various elements in a manner that creates a big picture of the time period. Regional or social histories have dominated this period in the last twenty years and perhaps it is time for a new attempt at integrating the various pieces of the puzzle into a coherent picture. This is not to dismiss the people and groups that make the story, but to put their story back into a greater context. The numerous books I read, when pieced together, accomplish this to some degree, but this manner is incomplete, as it does not, nor were the majority of the authors intending too, create a complete picture of what America was like in the early nineteenth century.

Outline and evaluate the psychodynamic model of abnormality. (12 Marks) The psychodynamic model (which is based on FreudÃ¢â¬â¢s theories) states that abnormalities are results of a conflict which has gone wrong in the Ã¢â¬Å"psycheÃ¢â¬ (in the mind). FreudÃ¢â¬â¢s idea states that the psyche Ã¢â¬â which is made up of the (id, ego and superego), should all work in perfect harmony with each other to avoid being an abnormal person. We will write a custom essay sample on Outline and Evaluate the Psychodynamic Model of Abnormality or any similar topic only for you Order Now It is the idea that conscious thoughts and feelings are determined by the unconscious mind, and essentially being mentally healthy requires a good balance between: the id (which controls the desires for which we live for in order to satisfy ourselves), the superego (which takes into consideration morals and the difference between right and wrong) and the ego (which balances the superego and id to keep our behaviour in check). From these 3 components in the psyche, you can quickly see that the id and superego are constantly in conflict. This ultimately means that for a person to not develop a psychological disorder Ã¢â¬â a strong ego is necessary as it will Ã¢â¬Å"get the best of both worldsÃ¢â¬ and create a balance, while allowing the superego and id to express themselves (when suitable), without dominating the personality and hence, causing a psychological disorder. An example of an abnormality which could occur from the id being too strong in kids (is developing conduct disorders). In adults (they become psychopaths), all because of the personality being taken over by the id. If the superego is too strong socially acceptable pleasures will be hard to come by as neurotic behaviours such as phobias and obsessions will be apparent, as they will be constantly fixated with things that they want to do but Ã¢â¬Å"cantÃ¢â¬ because their too scared. Freud thought that the childhood of an individual was essential in the development of personality and that all abnormal behaviours are linked to childhood. There are different ages associated with different stages. An example of this is the oral stage which usually happens between (0-18 months) Ã¢â¬â the focus of pleasure is the mouth (feeding or dummy) and if this is fixated upon, this could lead to overeating or smoking in order to comfort themselves and their mouth. Another example is the anal stage (2-4 years). A conflict may arise when potty training as if the child receives either excessive punishment or the parents are too lenient during this stage it can lead to a fixation which will be taken to adult life. The end result could either be a person who has an anal retentive personality (stubborn perfectionist obsessed with tidiness) or an anal repulsive personality (messy person with no self-control), according to Freud. The evaluation of FreudÃ¢â¬â¢s model is that many detailed pieces of data were obtained as it was a case study. The findings did support FreudÃ¢â¬â¢s hypotheses and theories. However FreudÃ¢â¬â¢s ideas were very subjective as not much Ã¢â¬â if any scientific data was produced to back his work up. This therefore raises question marks over the reliability of his findings and theories. Also the evidence from the case study came from his own patients who could compel us to think that his results are unreliable, as his patients may have been biased and essentially gave the answers Freud wanted, because they were his patients.
