A neutron breaks down to form a proton and an electron.

Change in atomic mass when an atom emits gamma radiation. The gamma radiation consists of photons which have no mass so the mass would remain the same.

Re the change in atomic number when an atom emits an alpha particle it loses two protons and two neutrons so the atomic number drops by 2.
