In a radioactive decay of a nucleus, an electron is also emitted. This may happen due to the fact that :

An electron is created at the time of conversion of a proton into a neutron

electrons are present inside a nucleus

an electron is created at the time of conversion of a neutron into proton

electrons need to be emitted for conservation of momentum
