Quizplus · Accepted Answer

Calcium (Ca) has two valence electrons in its outermost shell. In order to achieve a full shell and become stable, it will lose these two electrons to form a +2 ion, which will have a complete outer shell (the same as the noble gas, argon). Therefore, it will lose two electrons.
