Question

Briefly, compare and contrast nuclear fission and nuclear fusion.

Answer 1

Fission is used nowadays since it is technological and economically feasible

Fussion is very disscussed due to the high energy, high density requiremenets. Also it is dangerous. It is used in bombs but not in energy production.

Fussion = joining atoms/molecules (releases energy)

Fission = splitting atoms/molecules (releases energy)

Normally, fission does not occur in nature whereas fission occurs in the sun or stars

For fission, we require little energy for starting the process, for fussion, we require very high T which is dangerous

The fuel for fission is normally uranium

the fuel for fussion is normally Hydrogen isotopes
