Final answer:
The formula for the ionic compound containing sodium ions and nitride ions is Na3N.
Step-by-step explanation:
The formula for the ionic compound containing sodium ions and nitride ions is Na3N.
In order to make a neutral compound, three sodium ions with a charge of 1+ are required to balance out the single nitride ion with a charge of 3-. This is represented by the formula Na3N.
Other examples of ionic compounds include sodium chloride (NaCl), aluminum oxide (Al2O3), and calcium phosphide (Ca3P2).
