Nuclear Energy
Nuclear Energy
Energy then can be released if less tightly bound nuclei are transmuted into more tightly bound nuclei. Two such processes, which we have...
Binding energy per nucleon
As, some mass disappears in the formation of a nucleus in the form of mass defect. This loss in mass reappears in the form...
Gamma Radiations and Gamma decay
Gamma Radiations:
There are energy levels in a nucleus, just like there are energy levels in atoms. When a nucleus is in an excited state,...
Beta Particles and Beta Decay
Beta Particles:
A nucleus that decays spontaneously by emitting an electron or a positron is said to undergo beta decay. Like alpha decay, this is...
Alpha Particle and Alpha Decay
Alpha Particle:
Alpha particles are helium nuclei of nuclear origin. It carries 2 unit positive charges and its mass is about four times the mass...
Radioactivity
Radioactivity was discovered by A.H. Becquerel 1896 accidently.
Radioactivity was a nuclear phenomenon in which an unstable nucleus undergoes decay. This is referred to as...

A free neutron, unlike a...
Atomic Masses
The mass of an atom is very small, compared to a kilogram; for example, the mass of a carbon atom, 12C, is 1.992647 ×...
