Mg2+ is larger Now, as for the logic behind this problem...The first thing to do is recognize that Ca2+ (Calcium) has lost 2 of its electrons, therefore its valence electron structure is the same as Ar's (Argon). Ar is in the same row as Mg. The trend for atomic radii is increasing to the left and down. Atomic radius increases to the left because the atoms to the right have more particles in the nucleus than their counterparts to the left; thus, the electrons are drawn closer to the nucleus, and the atomic radius is diminished.
