    Their charges would be + 2. When Group 2 elements lose two electrons they form positively charged ions (+2) ions. Magnesium, Calcium, Beryllium Strontium and Barium, lose their electron form positively charged Mg2+, Ca2+, Ba2+, Be2 + Sr2 + ions. These elements lose their electrons to obtain a noble gas electronic configuration.
