here's your answer!!☺☺

Both Na+ and Mg2+ have the same number of electrons
in a configuration emulating Neon, the difference is Mg has
more protons in the nucleus attracting the electrons inward
thereby making Mg have a SMALLER atomic radius.

Hence, Na+ will be larger in size.

Answer 2

Deduce which of Na+ and Mg2+ is thesmaller ion. Explain your answer.mg2+ would be the smaller ion this isbecause 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.
