The active material provides the nuclear energy of the weapon. For fission bombs it is either Uranium or Plutonium. For fusion bombs it is normally Lithium Deuteride. There are many bomb designs that combine fission and fusion: a boosted fission bomb uses a hollow sealed fissile core that is filled with either deuterium gas, tritium gas, or a mix of both to get a small fusion yield, which causes a higher fission yield; the traditional fusion bomb involves several "cycles" of fission and fusion to work resulting in it usually being referred to as a fission-fusion-fission bomb, with typically 90% or more of its yield actually coming from the final fission step (not fusion).
plutonium and neutrons
For bombs such as atomic or nuclear, I believe it is a nuclear engineer.
yes it is.... it is the main part of a nuclear weapon.
Physicists and nuclear scientists create atomic bombs.
White phosphorus is used in some incendiary bombs (e.g. phosphorus and napalm), but not in any nuclear bombs.
plutonium and neutrons
Uranium, plutonium or hydrogen.
They were made by the United States during WW2.
Some bombs are nuclear. But most bombs are not nuclear.
40,000
china,russia,usa,uk!......
Never, at least not yet.
The nuclear material used to make the bombs was from Oak Ridge TN
None, the US currently only refurbishes existing bombs.
Yes, there is nuclear energy in nuclear bombs. It is released in a few microseconds when they are detonated.
Beacause millions of lives were taken by the nuclear bombs
No, China has several hundred nuclear bombs and has had bombs since 1964.
