Which of the following correctly identifies the cation and anion present in the compound NH4F?

• A. Cation: N^3-, Anion: HF^+
• B. Cation: NH4^-, Anion: F^+
• C. Cation: H^+, Anion: NH4F^-
• D. Cation: NH4^+, Anion: F^-

Answer: (D)

Verified step by step guidance

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