1) When an atom releases an alpha particle what happens to its mass number?
2) When an atom releases an alpha particle what happens to its atomic and proton number?
3) in beta decay what happens to the charge of the nucleus that released it?

1) Alpha is a cluster of 4 nucleons .. after it's release from the nucleus the mass number decreases by 4
2) Alpha removes 2 protons + 2 neutrons from the nucleus .. atomic number is the same as proton number .. it decreases by 2
3) When a Beta is formed a neutron decays to a proton .. the nucleus charge increases by 1 .. (by +1.60^-19 C)
