why is the atomic radius of Mg2+ bigger than that of Na+?

Answer Posted / patrick

Its not. 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.
