Explain β rays?

Submitted by: Muhammad
These rays consist of electrons. When the conversion of a neutron into proton takes place then an electron is ejected out, along with electron another particle is also ejected out which is known as anti-neutron. The mass of this anti-neutron in negligible. When a β ray is emitted by the parent element then the atomic number of the daughter is more by one unit than the parent element. However the mass number of both remains the same.
