How is the ionic charge of a group 1A,2A, or 3A ion determined?

Group IA elements have 1 electron in their outer shell.
Group IIA elements have 2 electrons in their outer shell.
Group IIIA elements have 3 electrons in their outer shell.

These elements lose 1, 2, or 3 electrons respectively, leaving ions with a charge of +1, +2, or +3.

If you have the ion ONLY, look at the charge on the ion. The charge WILL BE the charge on the ion.

OR have I not interpreted your question correctly?
