WHAT IS NUCLEAR FISSION?

Nuclear fission is the splitting of the nucleus of an atom into parts (lighter nuclei) often producing free neutrons and other smaller nuclei, which may eventually produce photons (in the form of gamma rays).

Fission itself is a nuclear process which does not usually occur naturally in nature as it requires a large mass and an incident neutron to start the reaction.

We cannot entertain multiple question of this type, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
