An element with a charge + 2 means it loses two electrons, whenever an atom or element has positive charge it means it loses electrons. + 2 charge means atom loses 2 electrons and now electrons are 10. so before there was 12 electrons and an element with 12 electrons means its atomic number is 12. An element with atomic number 12 is magnesium.
