Verified step by step guidance

Identify the ions present in the compound NH4CN. The formula consists of NH4+ (ammonium ion) and CN- (cyanide ion).

Recall that the name of an ionic compound is composed of the cation name followed by the anion name. Here, NH4+ is the cation ammonium, and CN- is the anion cyanide.

Combine the names of the ions to form the compound name: ammonium (for NH4+) and cyanide (for CN-).

Verify that the compound name matches the formula given, ensuring no other ions like carbonate (CO3^2-), nitrate (NO3-), or chloride (Cl-) are present.

Conclude that the correct name for NH4CN is ammonium cyanide.
