Gamma radiation is simply a high energy photon of energy. It has particle, unlike alpha and beta radiation.
Alpha radiation is the emission of a helium nucleus. This means a reduction in atomic number by 2 (two protons) and a reduction in atomic mass by 4 (two protons and two neutrons)
A beta radiation is an electron emitted by a neutron emitting an electron when turning into a proton. This doesn't change the mass, but does change the atomic number (up one)
Gamma radiation emits no massive particle and doesn't change a neutron into a proton or vice-versa, thus no change in mass or atomic number.

23, the protons are always the same as the atomic number, and the neutrons are the result of the atomic number subtracted from the mass number. For example 51-23=28 neutrons in the nucleus. The number of electrons is equal to the the number of protons, unless you have an ion. Hopefully that helps

Most certainly there is change of mass of nucleus,
eqaul to the energy carried away by γ-particle:
ΔM = -E/c² = -hf/c².
Atomic number is equal to electric charge of the nucleus,
and charge does not change, because γ-particle is
neutral and carries away no charge.

I don't think so. There is some loss.
