Nuclear Weapons




Chemical reactions come in many forms and the well known Nuclear Weapon, the "Atomic Bomb" is a weapon that uses Nuclear reactions. Fission or a combination of fission and fusion creates its destructive power. This nuclear weapon releases mass amounts of destructive energy. Its deadly power is comparable to more than a billion kilograms of high explosives. Even the smaller weapons are as devastating, annihilating cities to towns.

This is what it looks like:

This weapon is capable of doing this:



There are two basic types of nuclear weapon. The first kind creates its explosive energy through nuclear fission. This has been stereotypically called The A-bomb, or Atomic Bomb. This uses the fission type chemical reaction.

Fission type weapons use a chemical reaction by using nuclear chain reactions. This is done in two ways, the “gun” method, and the “implosion method. The gun method uses chemical weapons and uranium or plutonium to create its deadly explosion. First it shoots the chemical into another in a canister like container and the chemical reaction happens. The implosion method is done by compressing the material of both chemicals needed for the explosion till the density cannot hold and explodes pushing out the energy created making a devastating explosion.

"Gun" type method:


"Implosion" type method:

The second type of nuclear weapons is the nuclear fusion reaction. This is generalized to be called a thermonuclear weapon, or hydrogen bombs (H-bombs). Unlike fission weapons there is no limit to how much energy is released by these bombs.
