Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e - +.
This decomposition of the nucleus is referred to as radioactive decay.During radioactive decay an unstable nucleus spontaneosly decomposes to form a different nucleus, giving off radiation in the form of atomic partices or high energy rays.
When a nucleus ejects a beta particle, one of the neutrons in the nucleus is transformed into a proton. Since the number of protons in the nucleus has changed, a new daughter atom is formed which has one less neutron but one more proton than the parent.
When an alpha particle is emitted from a nucleus the nucleus losestwo protons and two neutrons. This means the atomic mass numberdecreases by 4 and the atomic number decreases by 2.(which is commonly known as alpha decay ) 
and by decaying the nucleaus will reach in a stable state ..
