What is the formula for the ionic compound containing sodium ions and nitride ions A) NaN B) Na₂N C) NNa₂ D) Na₃N E) NNa₃

Question

Quizplus · Accepted Answer

The formula for the ionic compound containing sodium ions and nitride ions is Na3N. The correct formula should have the same number of positive and negative charges, and the charges on Na+ and N3- are +1 and -3 respectively. Therefore, it takes three Na+ ions to balance the charge of one N3- ion, resulting in the formula Na3N. Choice D (Na₃N) is the closest to the correct formula, but it contains sulfur atoms which are not present in the compound.
