=INTRODUCTION=


 * //Nuclear chemistry can be used to create many different things. It can create power, some scientist use to make new medicines, and nuclear chemistry can even be used to form an atomic bomb. You might be wondering how nuclear chemistry might be able to be transformed to be used as a weapon of death. Well, an atomic bomb works by initiating a nuclear chain reaction. To cause a nuclear reaction a neutron must be shot at atoms packed tightly together, and these atoms must have heavy nuclei. When the neutron comes in contact with the nuclei, they break apart and become lighter and from this new neutrons are produced and begin to hit other nuclei causing a chain reaction. This process is interpreted as fission, because of the nuclei breaking apart.//**

=HOW DOES AN ATOMIC BOMB WORK?= //**
 * //An __atomic bomb__ works by initiating a nuclear chain reaction, which releases a huge amount of energy relative to conventional explosives. Per unit volume, an atom bomb may be millions or billions of times more powerful than TNT. When an atomic bomb occurs it creates a nuclear reactions which is when neutrons are fired at closely packed atoms with heavy nuclei (uranium or plutonium isotopes). These heavy nuclei break apart into lighter nuclei when hit by a neutron, in turn generating more neutrons which bombard other nuclei, creating a chain reaction. This process is known as fission. (Another process known as fusion releases energy by fusing together nuclei rather than breaking them apart.) By breaking down the nuclei themselves rather than releasing energy through a conventional chemical reaction, atom bombs can release more than 80 terajoules of energy per kilogram (TJ/kg).

=HOW DO YOU BUILD AN ATOMIC BOMB?=
 * //When building an atomic bomb, fission and fusion are processed where large amount of heat and radiation are given off.//**

//YOU WOULD NEED THE FOLLOWING://
> //**
 * **//A cource of fissionable or fusionable fuel//**
 * **//A triggering device//**
 * **//A way to allow most of the fuel to fission or fuse before the explosion occurs; or the bomb won't/wil not have any affect

=WHAT IS NUCLEAR FISSION?=

> > > >
 * //Nuclear fission is the splitting of the nucleus of an atom into parts (lighter nuclei) often producing photons (in the form of gamma rays), free nuetrons and other subatomic particles as by-products. Fission of heavy elements is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place). Fission is a form of elemental transmulation because the resulting fragments are not the same element as the original atom.//**

=WHAT IS NUCLEAR FUSION?= > > > [|][|=__//BIBLIOGRAPHY//__ [[http://hyperphysics.phy-astr.gsu.edu/Hbase/nucene/fusion.html|]= ]] = = = =
 * //If light nuclei are forced together, they will fuse with a yield of energy because the mass of the combination will be less than the sum of the masses of the individual nuclei. If the combined nuclear mass is less than that of iron at the peak of the binding energy curve, then the nuclear particles will be more tightly bound than they were in the lighter nuclei, and that decrease in mass comes off in the form of energy according to the Einstien relationship. For elements heavier than iron, fission will yield energy.//** **//For potential nuclear energy sources for the Earth, the deuterium-tritium fusion reaction contained by some kind of magnetic comfinement seems the most likely path. However, for the fueling of the stars, other fusion reactions will dominate.//**
