Identify the compound given: NH4F. This is an ionic compound composed of ions.
Recognize that NH4 is the ammonium ion, which is a common polyatomic cation with a charge of +1, written as NH4^+.
Recognize that F is the fluoride ion, a common monatomic anion with a charge of -1, written as F^-.
Confirm that the compound NH4F consists of the ammonium cation (NH4^+) and the fluoride anion (F^-), balancing the charges to form a neutral compound.
Therefore, the correct identification is: Cation: NH4^+, Anion: F^-.
