Ca(2+) ..... F(-)
CaF2 <<< 2 is a subscript
I can't draw a diagram on screen

Because Ca is in the 2nd column of the periodic table, it will lose 2 electrons and its ion will be Ca2+. Because F is in the next to the right column, it will gain one electron to form F-.
The compound will be CaF2 so that the two positive charges are neutralized by 2 F- ions.
