Half life of a radioactive substance is the time it takes for the given amount of substance to reduce to half as a consequence of decay.
T1/2 = 0.693/λ
Where T1/2 is the half life λ is the disintegration constant
Binding energy of a nucleus:
If a certain number of neutrons and protons are brought together to form a nucleus of a certain charge and mass, then the energy released is called the binding energy. Also, if we separate a nucleus into nucleons, we would have to supply a total energy equal to the binding energy.
