Isotope

Radioactive. Dangerous. Massive. The process of splitting the atoms of uranium is just that. Uranium is used in nuclear bombs and in nuclear energy. We know that nuclear bombs are the most deadly weapon on the face of the earth, but there is a positive way to use the uranium. We use uranium in our nuclear energy reactors to provide a clean energy for our power grids. “America’s 99 nuclear power plants generate almost 20 percent of the nation’s electricity while emitting no carbon dioxide or…

1. Matter can be found everywhere and anywhere. It is anything that takes up space and consists of mass. 2. An element is a substance that includes atoms. These atoms all have the same amount of protons. 3. A compound is formed when two or more separate elements combine and mix together. An example is pure table salt. Table salt is created by two elements which are sodium and chlorine. Sodium and chlorine combine and mix together until the end result which is the table salt. 4. Atoms are…

It occurs in three natural isotopes 2 19Rn (actinon), 220Rn (thoron), and 222Rn which is commonly referred to as radon. Thoron is produced in the thorium-232 decay series with its principle mode of decay being β (beta) particles. Actinon has a very short half-life of around 3 seconds and is only present in around 0.7% of natural uranium. 222Rn (radon) is the main radon isotope of concern. It occurs as a product of the radioactive decay of solid radium…

Many topics in chapter 13 Death and Dying, were delicate subjects for the healthcare community. Medicine and Healthcare has always had a strong emphasis on wellness. But, when discussing the legal definition of death either expected or unexpected can be an uncomfortable subject. In the topic explaining the” Criteria for Death” helped to educate myself on understanding death before donation. There are two types’ of death determinations for a person to be considered a candidate for organ or tissue…

Moles 1.How is molar mass calculated and why is it useful? Molar mass is calculated by going to the periodic table finding each mass of each element in the compound then adding them all up based on how many of those elements are in the compound. 2.Define a mole in chemistry and give 3 examples equivalent units that are used in chemical calculations. Mole is considered the unit for amount in chemistry other units that are equivalent are atoms, formula units, and molecules. Gas Laws 3.How is the…

potentially leak and when in the environment continue to release harmful radiation for extended amounts of time. The release of radiation in nature is due to decay and varies between elements because of their different half-lives. Nuclides (radioactive isotopes) are stable when they have enough binding energy. When elements are created separate nucleons are crushed to form a nuclide, during this process energy is lost, and this energy is binding…

In Cherry Lewis’s "The Dating Game", she analyzes the autobiography of Arthur Holmes, the English geologist known for his advancements in radioactive dating and theories on the Earth and how it has aged. To put it into perspective, the book tracks how ideas vary vastly over one man’s day. Arthur Holmes was an influential pioneer in the findings and research of his theory in the mid 1800's, so Kelly depicts his views as time has passed. Through the use of literary analysis, autobiographies, and…

1898. Neon was discovered at the University College London in London, England. Neon is a gas so it is colorless, odorless, and tasteless. Neon has 10 protons, 10 neutrons, 10 electrons. [He] 2s2 2p6 is the electron configuration. Neon has 3 known Isotopes. The atomic mass for Neon is 20.1797. Neon glows when a high electrical voltage is passed through it. Neon does not form compounds with other substances and it is odorless. The risk of inhaling Neon causes serious risk of suffocation or…

Uranium Paetyn Blockhus Why do you think people thought when they first discovered uranium? The warfare has changed when uranium was introduced. The discovery of radioactivity and other things in uranium has been discovered over the years. The size and weight of uranium is one of its many characteristics. The world had changed when they started using and mining uranium. The fun facts of uranium are truly surprising. Uranium is an…

The chemists' main objection focused on two isotopes of the element neodymium. By measuring the relative abundances of the isotopes in a rock, geochemists can tell whether the rock originated in the mantle lithosphere -- the slice of the North American jelly sandwich that, according to Bird, the Farallon Plate had dragged away. When the chemists checked the neodymium, however, the rocks proclaimed that the mantle lithosphere is very much intact. The evidence was compelling; many of Bird's…
