Explanation:

Radioactive decay: 

Radioactive decay is the spontaneous breakdown of the nucleus of an atom along with the release of energy and matter from the nucleus.

Beta Decay: 

Radioactive decay is when the parent nucleus emits an electron and an antineutrino and converts a neutron to a proton.

The equation for β-decay is given by:

 

Where X is the parent nucleus, Y is the daughter nucleus, is the atomic massis the atomic numbere- is the electron is the antineutrino.
