Aluminum Nitrate and Bonding Types

The video explains that aluminum nitrate (AlNO3) is an ionic compound overall, but contains covalent bonds within the nitrate ion. Aluminum, a metal, forms ionic bonds with the nonmetals nitrogen and oxygen. The video discusses the charges of ions, with aluminum having a 3+ charge and nitrate ions having a 1- charge, balancing each other to form the compound. The covalent bonds occur between nitrogen and oxygen within the nitrate ion.
