Which is the smaller atom: Mg or Mg+2?
Mg because it gains an energy level since it gains 2 electrons.
Mg due to extra electron repulsion created by gaining 2 electrons.
Mg+2 because of extra electron repulsion created by gaining 2 electrons.
Mg+2 because it loses an energy level since it loses 2 electrons.
