Deduce which of Na+ and Mg2+ is the smaller ion. Explain your answer.
mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus.
