Copper(II) Phosphate Charge and Bonding

The video explores whether copper 2-phosphate (Cu3(PO4)2) is ionic or covalent. It explains that the compound is ionic overall due to the metal (copper) and non-metal (phosphate) combination, but the bonds within the phosphate ion are covalent. The video details how to calculate the charges of the ions involved, emphasizing the attraction between positive copper ions and negative phosphate ions, resulting in an ionic bond. It also highlights the covalent nature of bonds within the phosphate ion itself.
