Which of the following is the correct name for the ion N^{3-}?

• A. Nitrate
• B. Nitrite
• C. Nitride
• D. Nitronium

Answer: (C)

Verified step by step guidance

1. Identify the ion given: \(\mathrm{N^{3-}}\) is a nitrogen ion with a charge of -3.
2. Recall common nitrogen-containing ions and their charges: Nitrate is \(\mathrm{NO_3^-}\), Nitrite is \(\mathrm{NO_2^-}\), Nitronium is \(\mathrm{NO_2^+}\), and Nitride is the nitrogen ion with a -3 charge.
3. Understand that the suffix '-ide' is typically used for simple monoatomic anions, such as \(\mathrm{Cl^-}\) (chloride) or \(\mathrm{O^{2-}}\) (oxide).
4. Since \(\mathrm{N^{3-}}\) is a monoatomic ion with a -3 charge, it follows the naming convention for simple anions and is called 'Nitride'.
5. Therefore, the correct name for the ion \(\mathrm{N^{3-}}\) is 'Nitride'.
