Isotope

cellular devices. Another use if for nuclear weapons, by building and using nuclear weapons we as a country can help protect ourselves and others. Nuclear uses uranium (the isotope uranium-235) in a controlled plant to split the atom (isotope) to create energy. The plant uses these process in water to ease the process, in where the isotope splits it releases neutrons and heat. This is a process that continues releasing even more neurons and heat. After this the heat is then used to spin a…

Atoms are the most basic building blocks, everything around us are made out of atoms. Atoms are so small that it can’t be found under the finest microscopes. A tiny spec of dust contains millions of billions of atoms! Even though atoms are tiny, but it actually consist of three different particles: protons, neutrons, and electrons. In every atom, electrons move around the nucleus, the combination of protons and neutrons. The idea of an atom was first discovered by the ancient Greeks, they…

actually discovered and named it argon in 1894. Argon burns blue, so it is used in what is typically referred to as neon lighting. It can be used to cool the heads of heat seeking missiles. It gets its name from greek word lazy. There are 22 known isotopes…

The way electrons go around the nucleus is the same way planets orbit. Elements have the ability to be present even with a varying number of neutrons. This is to be called isotopes. His point with this is that these isotopes are very balanced while others may be not so balanced. This will then be called radioactivity. Every isotope that becomes radioactive eventually decays. So to conclude this chapter, there are clocks for all forms of time. Chapter 5 Dawkins is talking about some very well…

When Charles Darwin exposed his theory of evolution for the first time, criticism soon aroused. The period 's mindset highly motivated the struggles for acceptance of Darwin 's theory. In other words, by the 1800s, the notion of an old Earth filled with evolving species dating back from billions of years contradicted religious beliefs and was far beyond everything concluded by other scholars. Although his book soon attracted the attention and support of many scientists to his new “Darwinistic”…

The third energy level has 18 electrons. The fourth energy level has six valence electrons. Selenium has forty-five neutrons. Selenium has the atomic number of thirty-four. The atomic mass is 78.96 for Selenium. It has 20 isotopes. The most stable isotope is Se (Selenium). Selenium is in the Chalcogen family. The Chalcogen family consists of Oxygen, Sulfur, Selenium, Tellurium, and Polonium.…

of the products and 3 neutrons. What is the missing isotope produced in this nuclear fission reaction? Write the complete nuclear fission reaction.…

and resists oxidation when exposed to air at standard temperature and pressures. It’s also found in over 30 different minerals; for example, minerals like aquamarine and emerald are the most precious forms of Beryl. Beryllium only has one stable isotope, with a melting point of 1280 on, and the boiling point of 2970 on. Even though Beryllium has a sweet taste to it, it is very…

days. (talk about iodine 131’s importance). In Seaborg’s life, the meaning of this element held major importance due to its aid in his mother’s cure of hyperthyroidism. Seaborg and Jack also discovered cobalt 60, which is also a critical medical isotope. Cobalt 60 emits gamma radiation which in turn focuses directly on cancer cells to destroy it. “Hundreds of thousands of Americans have had their cancers treated by cobalt-60 irradiation, and it is also used to sterilize medical products and…

a higher atomic number. Nuclear fission, on the other hand, is the “splitting of a nucleus into smaller fragments, accompanied by the release of neutrons…” For example, uranium-235 and plutonium-239 are fissionable isotopes. In fusion reactions deuterium and tritium, hydrogen isotopes, are combined to form a helium nucleus. Although fusion is a very desirable process, the reaction is unpredictable. The necessity of obtaining and maintaining a high temperature whilst the reaction occurs is…
