all elements are trying to be like the noble gases
elements in group 2 have 2 electrons in their outer shell
therefore, they can either gain 6 electrons (charge -6, because there would be 6 more electrons than protons) or they can lose two electrons (charge +2, because there are two more protons than electrons)
it is easiest for the element to lose 2 electrons than gain six
therefore the charge is +2

On a group 2 ion the charge is 2+.
e.g. Calcium ion is Ca2+

a group 2 element has 2 electrons in its outer shell, and to become totally stable it wants a full outer shell, as its easier to lose 2 then gain 6 it loses these 2 electrons and as an electron as a -1 charge, loosing 2 of them means an overal charge of +2

think about it. all elements want to be like the nobel gases. is it easier for them to gain or lose electrons to get there. now you can answer your own question.

2+ baby. like Ca2+.

Indeed it is as simple as +2!
Get an "A".
