You need to specify what kind of name before anyone can answer this? ALuminum is aluminum and Nitrate is a polyatomic ion.
Nitrate Ion
Chromium (III) Nitrate
The polyatomic ion in KNO3 (potassium nitrate) is NO3- , the nitrate ion. This ion is polyatomic because it contains four atoms bonded together. The nitrate ion is derived from nitric acid, HNO3.
Aluminum nitrate is slightly acidic because the hydrated aluminum ion, Al(H2O)63+ is slightly acidic. It dissociates according to the following equation. Al(H2O)63+ --> H+ + Al(H2O)5OH2-.
Al3 --> aluminum ion HPO4 2- --> hydrogen phosphate ion v^_^
Aluminium almost always forms the +3 oxidation state in its compounds, so we do not use a Roman numeral when naming aluminum compounds. The NO3 moiety is the nitrate ion, NO3-. So the name is aluminum nitrate.

Aluminum (Al) is a +3 metal, and nitrate (NO3) is a -1 polyatomic ion. In order to cancel out the charges, you need 3 nitrates for every 1 aluminum, so the correct formula is Al(NO3)3.
The nitrate ion is NO3-
Nitrate ion: NO3-

The nitrate ion is NO3-
The nitrite ion has one less oxygen atom.
The standard name of this compound is Nitrogen(II) Oxide. It is generally known as nitric oxide.
