Fluorine can only form fluoride ions, F- ; it never gives off one or more of its electrons.
Metals only form positively-charged ions and may be found to the left of the "stair-step line" that wiggles through the periodic table on the right side.

When an element forms a negative ion, the name changes to IDE, fir example: chloride
Chlorine, the halogen in period 3.
Bromine is the only element that matches this description.
Depending on the element the furthest shell out, when the outer shell has been filled by an other element donating one electron it turns into an ion.
Calcium
The third period element that forms a 3- ion is sulfur.
potassium
The ion is awesom
Sodium forms 1 type of ion; namely, Na+.
