Simply put, nuclear fission is the splitting of an atomic nucleus. It relates to radioactivity in that some isotopes of some elements (and not very many) naturally decay by spontaneous fission. There is a separate question about what spontaneous fission is, and it is linked below.
Nuclear fission is the process where an atom (for example Uranium) is split by bombarding it with a neutron. As this results the atom (with the neutron) which is not in the ground state splits into two or more new atoms. Imagine a billiards game where 2 balls are laying against each other (this is one atom), now you shoot the white ball against them and they split. Approximately 200 MeV are released in the process. Nuclear fission is directly related to a nuclear bomb but unlike a nuclear power plant, the process is not controlled because you want as much energy released as possible.
This nuclear weapon is called an atomic bomb or a nuclear bomb
Nuclear fusion is the phenomenon in which two lighter nuclei get fused to form heavier nucleus with the production of energy. Best example is SUN and hydrogen bomb. But nuclear fission of breaking heavier into lighter with the emission of energy. Example uranium-235. So atom bomb Nuclear fusion has clean energy but fission has hazard energy
They have a starter in a bomb and what this will do is shoot a neutron in the nuclear fuel starting a chain reaction
No, the bomb dropped on Hiroshima was an atomic bomb using uranium as the fissile material.
Nuclear fission is used in nuclear weapons to create what some might call an atomic blast (nuclear blast). Nuclear fission used this way can also be applied in special complex designs to generate enough thermal energy (heat) to initiate a fusion reaction. This creates an even bigger nuclear blast.
The fission bomb is known as the Nuclear bomb, or the A-bomb

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.
Nuclear fission
Atomic fission bomb.
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.
