Answer

Explanation:

Step1: Determine charge - balance

To form a neutral compound, the total positive charge from cations must equal the total negative charge from anions. The charge on $Fe^{3 + }$ is + 3 and the charge on $N^{3 - }$ is - 3.

Step2: Find the ratio

To balance the charges, we need 1 $Fe^{3+}$ ion and 1 $N^{3 - }$ ion. So the cation - to - anion ratio is 1:1.

Step3: Write the formula

The chemical formula of iron(III) nitride with a 1:1 ratio of $Fe^{3+}$ and $N^{3 - }$ is $FeN$.

Answer:

cation to anion ratio: 1 : 1 Compound formula: $FeN$
