Isotope

dietary supplements. The mineral zinc is found in the periodic table with the symbol ZN and has an atomic number of thirty. Zinc is one of the more abundant elements in the Earth’s crust, the twenty-fourth most abundant, and it contains five stable isotopes. This mineral is also known as an essential trace element, meaning the human body only requires a small amount to be considered healthy. One of the health benefits of zinc includes boosts in the immune system, by fighting if bacteria and…

The destructive history of atomic wars interested me in how an atomic bomb works. Atomic bombs use either Uranium 235 or Plutonium 239. What makes these two elements particularly special out of the 118 known elements is that they have unstable isotopes.…

Soon, Compton became more involved with human problems, his interest soon led him to the greatest challenge of his life and leadership responsibility. During World War II, physics research had changed drastically, especially for Compton. Compton became involved in the “uranium problem” that led to the evolution of nuclear reactors and soon after, the atomic bomb. On November 6th, 1941, Compton introduced a report on the military uses of atomic energy with the help of physicist, Ernest O.…

Berkeley's Ernest O. Lawrence. The atom bomb changed the world in multiple ways. It led to the creation of "artificial radioactivity". Artificial radioactivity is when radioactivity has been produced through the bombardment of naturally occuring isotopes by subatomic particles or by a high level of x-rays or gamma rays. It led to the end of World War II. After Hiroshima and Nagasaki…

Did one single disaster cause the K-T extinctions? Some scientists and people are committed to just one reason the K-T extinctions occurred but in this paper many possibilities will be explored with evidence to back up why they could have been a cause as well to the extinctions. Everyone will ultimately make his or her own decision/thoughts on what could have happened, and of course all hypotheses would be subject to analysis. Asteroid impact theory. The impact of a 10 km+ asteroid would blow a…

he intent of the paper is to give the reader a closer examination of a variety of Medical Imaging modalities that are being used today. A short rundown is presented for Interventional Radiography, Nuclear Medicine, Mammography, Magnetic Resonance Imaging, Ultrasound, and Radiation Therapy. Following is a more in-depth look at Computed Tomography that will give the reader a better comprehension of how it separates itself from other medical imaging specialties. Interventional radiology: The…

correct answer from the choices below. 1. The mass of an atom expressed relative to the mass of? A. Carbon-6 C. Carbon-12 B. Carbon-10 D. Carbon 2. It is defined as the number of atoms of that element equal to 12.0 grams of an isotope of Carbon. A. Molar Mass C. Particles B. Stoichiometry D. Mole 3. The first step in every Stoichiometry Problems is to? A. Balance the equation C. Solve the mass of the element/compound B. Determine the Limiting…

In the 21st Century there are several energy production methods, they can be cheap yet inefficient or expensive and more efficient. However, fossil fuels are used because they are efficient and easy to acquire, but they affect the environment. Coal-Fired electricity production has been around since the Industrial Revolution, this means that coal-fired electricity that still makes up 61% of the electricity produced in Australia (Department of Industry and Science, 2015). Therefore, it makes…

a man-made radioactive element that is made from uranium in nuclear reactors (Environmental Protection Agency, 2014). Much of the plutonium made was to be used for nuclear war. When plutonium decays it releases radiation. So do the other forms of isotopes. The half-live of these radioactive metals is anywhere from 87.7 to 6,560 years long (Environmental Protection Agency, 2014). One of the environmentally harmful violations, that Karen witnessed, was a truck being cut up into pieces small enough…

Nuclear power is one of the biggest producer of the electricity in the world. In 2014, Nuclear power plants generated approximately 11% of total world electricity supply. Many futurist predict that by 2050 it could provide up to 35 percent of global electricity. There are many nuclear power plants around the world and many more are in process of building. Currently there are 438 nuclear reactors in 30 countries and 67 new nuclear plants are under construction in 15 countries. History The…
