Having recently needing to answer this question on an online homework, the answer is simpler than expected. The question is really just asking for the "symbol" of fluorine which is F-
Another example would be if it asked, "Predict the ion formed by Na (sodium)." The answer would simply be Na+
Fluoride ion (F-) is not an element, but an ion formed from the element fluorine (F). Fluorine is a chemical element on the periodic table, while fluoride ion is a negatively charged particle resulting from the gain of an electron by a fluorine atom.
The only possible ion of fluorine is: F-It's called a fluoride ion.
The symbol for fluorine as an ion is F-.
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
Ammonium fluoride is an inorganic compound, specifically a salt. It is formed from the combination of the ammonium ion (NH4+) and the fluoride ion (F-).

The ion formed by chlorine is the "chloride" ion
The conjugate base is the fluoride ion, F-
The symbol for fluorine as an ion is F-.
Hydroxonium H3O+ ion is formed.
The smaller ion is F.
+1 Na+ ion is formed
NH4F is a salt formed from the reaction between ammonium ion (NH4+) and fluoride ion (F-). Ammonium ion is acidic, while fluoride ion is basic. Therefore, NH4F tends to be slightly acidic due to the presence of the acidic ammonium ion.
Fluoride Ion
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
