Ions such as fluorine always have a Negative charge- when looking at the Periodic Table you will see groups 8,7,6,5,4 and 3 on the right side. All noble gases in Group 8 have no charge, but going to the left:
7 = -1 charge
6 = -2 charge
5 = -3 charge
4 = -4 charge
This only works for nonmetals, not transition metals so be careful.
So, looking at Fluorine it is in Group 7
7 Nonmetals always have a -1 charge.
2 Fluorine Ions * -1 = -2
-2 is your answer. When it meets with a positive ion (Groups 1 and 2 on the left side of the periodic table), the two charges will need to balance. So the positive ion will need to be +2. This can happen naturally (positive ions in Group 2 are +2, so 2F and 1Ca will work) or because there are enough positive ions to balance the charge (positive ions in Group 1 are +1, so having 2F and 2Na will work).
Good luck :)
