Verified step by step guidance

Identify the cation and anion in the compound Al(NO3)3. The cation is Al, which is aluminum, and the anion is NO3, which is nitrate.

Determine the charge on the aluminum ion. Aluminum typically forms a +3 charge, written as Al^{3+}.

Recognize that nitrate is a polyatomic ion with the formula NO3^{-} and a charge of -1.

Since there are three nitrate ions to balance the +3 charge of aluminum, the compound is named by combining the cation name 'aluminum' with the anion name 'nitrate' without needing to specify the charge in parentheses because aluminum has a fixed charge of +3.

Therefore, the correct name for Al(NO3)3 is 'aluminum nitrate'.
