Question

Difference between nuclear fusion and nuclear fission

At lest 5 differences

Answer 1

In nuclear fission, the nucleus of heavy atom(uranium or thorium), when bombarded with low-energy neutrons, can be split apart into lighter nuclei. When this is done, a tremendous amount of energy is released.

Nuclear fusion means joining lighter nuclei to make a heavy nucleus, most commonly hydrogen and its isotopes to create helium.
It releases lot of energy. Millions of degrees of Pascal of pressure is required.
