Answer 2

Indeed, the given formulas for ions are incorrect. I'll correct them for you:

Correctly written formulas for ions:

1. S^2- (Sulfide ion)
2. Mg^2+ (Magnesium ion)
3. F^- (Fluoride ion)
4. Ba^2+ (Barium ion)
5. NO3^- (Nitrate ion)
6. NH4^+ (Ammonium ion)

Please note that in chemical formulas for ions, the charge is indicated as a superscript and should not have a space between the element symbol and the charge.
