Answer:
[tex]\boxed {\boxed {\sf AlN}}[/tex]
Explanation:
The goal when forming compounds is to achieve a net charge of 0.
We are given aluminum with a charge of 3+ and nitrogen with a charge of 3-.
These charges are equal and opposite, so one of each will equal 0.
Therefore, we do not need any subscripts. List the metal's symbol (aluminum) then the nonmetal.
Th formula for the compound, which is aluminum nitride, is AlN.
