Nuclear weapons

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or from a combination of fission and fusion reactions

Nuclear weapons

Fission weapons. All existing nuclear weapons derive some of their explosive energy from nuclear fission reactions. Weapons whose explosive output is exclusively from fission reactions are commonly referred to as atomic bombs or atom bombs (abbreviated as A-bombs).



How does a nuclear bomb explode?

"This is known as a chain reaction and is what causes an atomic explosion. When a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons and some binding energy. Two neutrons do not continue the reaction because they are lost or absorbed by a uranium-238 atom."


How did the atomic bomb work?

"Nuclear fission produces the atomic bomb, a weapon of mass destruction that uses power released by the splitting of atomic nuclei. When a single free neutron strikes the nucleus of an atom of radioactive material like uranium or plutonium, it knocks two or three more neutrons free."


Why was the A bomb dropped?

"The reasons Hiroshima was chosen as the target for the A-bombing are assumed to be the following. The size and the shape of the city was suited to the destructive power of the A-bombs. Because Hiroshima had not been bombed, ascertaining the effects of the A-bomb would be relatively easy."
