Copper II Nitrate Properties and Bonds

The video explores whether copper II nitrate (Cu(NO3)2) is ionic or covalent. It concludes that copper II nitrate is an ionic compound overall, due to the presence of a metal (copper) and non-metals (nitrogen and oxygen). The nitrate ion within the compound has covalent bonds between nitrogen and oxygen. The video explains the charges on the ions, with copper being 2+ and nitrate being 1-, resulting in an ionic bond between the positive copper ion and the two negative nitrate ions. The nitrate ion itself is a covalent compound, also known as molecular.
