WebWhy protons Cannot gain or lose? It couldn't possibly have taken on additional protons because protons and neutrons are bound by the strong nuclear force, which keeps the nucleus stable. Instead, we look to the loosely bound electrons. Electrons are not as tightly bound as nucleons and can be kicked out of the atom given sufficient energy.
