No, the magnesium ion will be smaller, as the outer electrons will be pulled closer to the nucleus by the higher nuclear charge.

If you're talking about whether they have the same number of electrons, that's something you can find on the periodic table. If I'm not mistaken, Sodium and Magnesium have a fairly small difference, and we're talking about a positive ion of Sodium. It's a possibility, but I don't remember what their beginning numbers are.

Sorry.
