Which group/family of elements will most likely form ions with a charge of - or 1-?

Re: Most likely charge for ions. Group 1 elements generally have a charge of +1 when they form ions, Group 2 has a charge of +2, Group 13 has a charge of +3. Group 17 has a charge of -1, Group 16 has a charge of -2, Group 15 has a charge of -3. So Rb would be +1, Ga would be +3, and S would be -2.
