The control rods are what give a steady output of energy after the fission process has taken place. They control the number of spare neutrons as a great amount are produced during a chain reaction with the nuclei. These control rods are usually made of the material cadmium or boran and they absorb excess nuclei in order the control the amount of free flowing neutrons so they do not become to excessive which would create larger amounts of heat. The rate that the energy is produced can be changed…

CALCIUM Calcium is a mineral found in many foods. The body needs calcium to maintain strong bones and to carry out many important functions. Not having enough calcium can cause many health problems. Calcium insufficiency also causes weak bones and tooth decay. This is because almost all calcium is stored in bones and teeth. This program will help you better understand the importance of calcium in the body and how you can make sure you are getting the right amount. Calcium is the chemical…

Lise Meitner was a physicist in scientist, who was recognized for the discovery of “nuclear fission”. She was the third of eight children from a Jewish family. She was a female scientist of the early twentieth century, who was devoted to work in science, she sacrificed many things like her family and person relationships for the benefit of her work. She was one of many women who were not recognized for something they discovered. Meitner was the physicist who discovered the splitting of an atom,…

London with Sir William Ramsay, the British chemist most known for discovering the noble gases. At the University College of London in 1904, Hahn made his first big discovery and contribution by discovering radiothorium, a radioactive isotope of thorium. In late 1905, Hahn moved to the Physical Institute of McGill University in Montreal, Canada. Here he worked with Ernest Rutherford, famous father of nuclear chemistry and many other chemistry achievements. Hahn during this time under Rutherford…

have. One of the new reactors is the Molten-salt reactor. This type of reactor is more efficient and is less likely to have a meltdown because it can cool the reactor much faster (Martin). Another technology that has long been talked about is a Thorium based reactor…

Humanity is in a race against time as the threat of global warming looms on the horizon. To prevent catastrophe, the nations of the world must focus on decreasing their carbon dioxide output by as much as possible. While agriculture and industrial processes have a high carbon footprint, fossil fuels are by far the biggest contributor to anthropogenic global warming. Therefore, the best way to mitigate the problem is to replace coal and oil with cleaner sources of energy. Solar and wind power are…

The element Magnesium got its name when it was discovered. It is a silvery white metal that is highly reactive. Its chemical symbol is Mg and atomic number is 12. Its atomic mass is relatively 24. Therefore, it has 12 protons, 12 neutrons, and 12 electrons. According to Steve Gagnon in “The Element Magnesium” Magnesium was isolated by Sir Humphry Davy, an English chemist, through the electrolysis of a mixture of magnesium oxide and mercuric oxide in 1808. Magnesium has a melting point of 650°…

energy needs for at least the next 100 years at present consumption levels. More efficient fast reactors could extend that period to more than 2,500 years. Also, even if we run out of uranium, thorium is also a nuclear fuel that is even more abundant than uranium; by the way, other than being abundant, thorium is very hard to turn into nuclear weapons and is less wasteful than current nuclear reactor…

commend. For instant, both have in commend when it comes to food. However, they different when it comes to their traditions. By the same token, Florida and Nicaragua have their different when it comes their typical food. In addition, when it comes to thorium their have many places to visit to spend time with the family. Additionally, they have different ethnicity. Equally important, when it comes to the language. Nor, Nicaragua and Florida have different life style when it comes to their why of…

story by mentioning other elements that changed when expose to extreme temperatures, ending the chapter with a discussion on yttrium (Y) and neodymium (Nd). In the seventeenth chapter, starts with Donald Glaser, the drunk who was interested in bubbles. Surprisingly, Glaser won a Noble Prize at the age of Thirty-three after he switched his research from bubbles in beer to bubbles in liquid nitrogen (N2). Kean also mentions Ernest Rutherford, who was interested in radioactivity. Rutherford mimic…
