You mean what triggers the fission chain reaction?
The atomic bomb that was dropped on Hiroshima was a gun style fission bomb that used a uranium-235 core. The core consisted of two hemispheres of U-235 on each side of a tube, with an explosive that would push them together. When they collide, they reach the critical mass for an uncontrolled chain reaction and nuclei start to split and release neutrons which will collide with other nuclei and split them as well. The explosive used to trigger the reaction is triggered by a detonator.
Nuclear fission
No, an atomic bomb uses fission, but a nuclear or thermonuclear bomb combines fission and nuclear fusion. Therefore, a nuke is more powerful than an atom bomb.
Yes, radioactive decay results in the release of nuclear energy. The radioactive decay of an atom is the result of changes in the atom's nucleus, so energy released will be nuclear energy by definition.
The term atom bomb (or atomic bomb) usually refers to a bomb that obtains its energy solely through the process of nuclear fission.However technically the term is considered interchangeable with nuclear bomb, and can refer to any bomb obtaining its energy through either nuclear fission, nuclear fusion, or any combination of the two processes.
Yes. Later, the Hydrogen Bomb used fission/fusion.
Nuclear fission
A nuclear bomb or atomic bomb
Atomic fission bomb.
Two atomic bombs, a gun-triggered uranium fission bomb, and a plutonium-core trigger fission bomb.
An atomic bomb is a bomb that releases a tremendous amount of energy by initiating a nuclear fission chain reaction.
This nuclear weapon is called an atomic bomb or a nuclear bomb

uncontrolled nuclear fission and/or fusion.
If you are asking which has the maximum danger, a hydrogen bomb is one type of nuclear bomb. In general, nuclear bombs can be fission (called atomic) or fusion (hydrogen) A fusion bomb is larger than an fission bomb, and actually uses a fission bomb to start the fusion reaction.
Fission bombs use fission. Fusion bombs use fusion. Although atomic bomb is usually used for fission bombs, it technically applies equally to either.
An atomic bomb uses nuclear fission at the atomiclevel to detonate several tons of explosives.
