Answer:

Mg has a greater size. In Mg2+, there are excess protons over electrons( 12 protons and 10 electrons). The effective nuclear charge experienced by the valence electrons is greatest in Mg2+ than in Mg. Hence the valence electrons in Mg2+ are pulled more closely to the nucleus than in Mg. This gives Mg are greater size
