Description : How many electrons does Ca plus gain or lose?
Last Answer : You already gave the answer yourself. You see, ions don't change the number of protons and neutrons of an atom. It only changes the number of electrons. Ca originally has 20 electrons, protons, and ... of protons and neutrons can change in an atom, is by the process of nuclear fission or fusion.
