Detailed explanation-1: -When a nucleus fissions, it splits into several smaller fragments. These fragments, or fission products, are about equal to half the original mass. Two or three neutrons are also emitted. The sum of the masses of these fragments is less than the original mass.
Detailed explanation-2: -A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about 3.6 × 1011 kJ of energy per mole of He42 produced.
Detailed explanation-3: -The mass converted to energy in fission is about 0.1%; in fusion it can be as much as 0.7%. These numbers apply whether the process takes place in reactors, bombs, or stars.
Detailed explanation-4: -In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.
