A particle doesnot have an atomic number. But what you are referring to is a Beta particle, an electron emitted from the nucleus and thus increases the atomic number of the nucleus by 1. Its mass is negligible compared to a proton or a neutron and hence the mass number does not change.
Example is conversion of U238 to Np239 and then to Pu239 by absorption of a neutron and emission of two beta particles (electrons). Another example is conversion of Th232 to U233 through a neutron absorption and beta emission.
