Neutron activation analysis

Atomic bombs work by splitting the nucleus of an atom. When the neutrons of the atom's nucleus split, some hit the nuclei of nearby atoms, splitting them too (Hydrogen). The result is a very explosive chain reaction. Thermonuclear bombs start with the same process that powers atomic bombs, but most of the uranium or plutonium…

The atomic number to my element is 11, the mass number is 23, the number of neutrons is 12, the protons are 11 and the electrons are also 11, the electron configuration of my element is 1s22s22p63s1. The person who discovered my element is Humphry Davy. He discovered sodium in 1807. Origin of sodium is derived from the English word ‘soda’. The appearance of sodium is soft metal that tarnishes within seconds of being exposed to the air. It also reacts vigorously with water. Used as a…

of 1 kg (2.2 lb) of uranium-235 discharges 18.7 million kwh as warmth. Second, the splitting procedure started by the retention of one neutron in uranium-235 discharges around 2.5 neutrons, on the normal, from the split cores. The neutrons discharged in this way rapidly cause the splitting of two more particles, in this manner discharging four or more extra neutrons and starting a self-supporting arrangement of atomic partings, or a chain response, which brings about ceaseless arrival of atomic…

chemistry into this chapter. He brings up the Bohr model, he states atoms being similar to the solar system. 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…

SEM is a kind of microscope to observe the topography of materials. SEM has some advantages: it has a large depth of field and we can observe the 3D image of the sample and analyzing its topography, its magnification range is widely and we could make sample easily because of the X-ray spectrometry, which can determine the elements of sample. When electron beam attack the sample, incident electron will be diffracted and change the direction or even loose some energy. During this process,…

their relative masses and charges (Bbc.co.uk 2015). Particle Relative Charge Relative Mass Proton +1 1 Neutron 0 1 Electron -1 2. Explain the meaning of the terms, ATOMIC NUMBER and MASS NUMBER of an atom in terms of sub atomic particles. The atomic number refers to the number of protons in an atom, the mass number refers to the number of protons plus the number of neutrons (Bbc.co.uk 2015). 3. A neutral atom contains the same number of protons and electrons. Briefly explain…

not normally occur naturally in nature. This type of reaction takes place when a large unstable isotope, usually Uranium, U-235, comes into contact with high speed neutrons. When they collide, fission takes place and in the process breaks down into smaller isotopes, high speed neutrons and a large amount of energy. These high speed neutrons strike more atoms which causes a fission trigger chain reaction that is self-sustaining. The energy created by fission is then used to heat water to steam…

that could possibly cause cancer. At which human health is more important than energy.Another problem fission suffers is the fact that disposing the waste is a challenge and if not done properly it can be hazardous to the people. The high energy neutrons that are produced by the fission reactions can make non radioactive substances that would be in the reactor and make them…

Nuclear power, we have all heard of it. Or most of us have, nuclear power is created by nuclear fission (“Nuclear Power for the 21sr Century”). The process of uranium isotopes in a controlled environment being split. As you know any action takes energy and when energy is being used or changed a by-product is made. In most cases it is thermal energy, which is heat energy. That is exactly what is happening in a nuclear power plant. When one uranium isotope is split a chain reaction is created in…
