Neutron

And how neutrons that can break chemical bonds in your body are captured by special screening that are placed inside the reactor contain special nuclei to prevent the spread of harmful neutrons. The truth is, nuclear reactors do not output harmful death-rays over hundreds of miles that slowly kill you, as anti-nuclear groups make it seem. As well, he…

and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to act as a source, moderator and reflector of neutrons. It can be forged, rolled and extruded, machined, punched, sheared and casted by vacuum casting. Commercially, it is available in block, rod, sheet, pebble, metal disk, foil and powder form. Beryllium…

When reading both Gourevitch’s text about the effects of the Rwandan genocide and reading Bana’s letter where he expresses how he takes responsibility for his crimes, both readings reveal ideas of responsibility and complicity. Gourevitch explains the way poor Hutus were responsible for the killings during the genocide. However, the financiers in high power were accomplices for ordering them. Bana’s letter conveys how only he and his colleagues took full responsibility of their crime without…

798. They found how many protons it has, 36. They found how many neutrons it has, 48. They also sound the number of electrons, 36. Then last but not least the gave it a symbol (Kr) and an atomic number of 36. Krypton was originated from a Greek word: Kryptos-- which meant “hidden.” After a series of test, the chemist…

Gilbert Lewis first introduced his theoretical dot structures in 1916. Today, these same dot structures are used to illustrate the chemical bonding nature of atoms. How did Lewis formulate these brilliantly simple representations of nature? The Lewis Dot Structures we know today actually derive their functionality from Lewis’ own model of the atom, the Theory of the Cubical Atom. This essay will explore the functionality of Lewis’ cubical atom and how this model led to the Lewis Dot Structures.…

The research paper first described the structural evolution of Iron Phosphate, FePO4 from temperature 294K to 1073K, in α phase and in its ß-quartz type. There are both similarities and differences in the crystal chemical relationship between quartz (SiO2) and FePO4. The structural parameters of α-FePO4 at low temperature range skews towards the parameter values for ß-quartz type when it is at high temperatures. Angles between elements Fe, O and P increase whilst tilt angles decrease…

2.4. Sucrose crystal structure Crystal habit is the term used to describe the appearance and shape of a crystal (Morel du Boil 1985). The conditions during growth of the crystal influence the development and morphology of the crystal. The morphology of a crystal grown in the presence of impurities is influenced greatly at the faces of the crystal most affected by the adsorption of impurities (Morel du Boil 1985). Therefore, the presence of impurities was thought to possess the greatest…

Elsa Gaston 1. Why is U-235 (the uranium isotope with a mass of 235 amu) a special element and what is it used for?- Under some conditions U-235 can be spilt and yield a lot of energy. It can be used for nuclear fission. 2. Describe nuclear fission and how the famous equation E = mc2 relates to this process?- It is when the nucleus of an atom splits into smaller nuclei or fission products. It is an exothermic reaction and a lot of energy is released. It is the equation that is in accordance…

His concept hinges on neutron stars, which are massive collapsed stars the size of Manhattan but with the mass greater than that of Earth’s sun (Kaku). Kerr postulated that if these dying stars collapsed into a rotating ring of neutron stars, their force would prevent them from combining into a singularity. Since this black hole wouldn’t have a singularity, Kerr believed it would…

What is Nuclear energy In the terms of theoretical physics energy is the ability to do work. You apply force and you get displacement. In a more practical world energy is heat, electricity, light etc. Per the theory of thermodynamics; energy is never destroyed it is changes form. I.e. heat/thermal energy converts to mechanical energy to move a car, nuclear energy to electric energy. Two major energy sources that the civilization requires now-a-days are, electricity and heat. Sun, the source of…
