Sure! I'd be happy to help you understand how to name ionic compounds. When naming ionic compounds, you need to consider the charges of the ions involved.
In the question you provided, there are two ions involved: Al³⁺ (aluminum ion) and N³⁻ (nitride ion).
To name the compound, you need to follow a few rules:
1. Write the name of the cation (metal ion) first, in this case, aluminum.
2. Write the name of the anion (non-metal ion) second, in this case, nitride.
3. To indicate the ratio of the ions, you need to use the numerical prefixes.
Based on the numbers you see by the symbols:
- Al³⁺ indicates that the aluminum ion carries a charge of +3.
- N³⁻ indicates that the nitride ion carries a charge of -3.
Now, you need to balance the charges of the ions. Since aluminum is a metal and tends to lose electrons, it will lose three electrons to become Al³⁺. On the other hand, nitrogen is a non-metal and tends to gain three electrons to become N³⁻.
Since the charges are already balanced, you don't need to use any numerical prefixes. The compound is simply called "aluminum nitride."
In summary, the name of the ionic compound is "aluminum nitride." The numbers next to the symbols indicate the charges of the ions, which you need to balance to determine the correct formula and name of the compound.
