"The relative numbers of protons and neutrons can differ before and after the change, but the total number of those particles remains the same."

Reason: in nuclear reactions the total number of nucleons (protons + neutrons, the mass number) is conserved, though protons and neutrons can convert into one another (so their relative numbers can change).
