Magnesium Phosphate Bonding and Properties

The video explores whether magnesium phosphate (Mg3(PO4)2) is ionic or covalent. It explains that while the compound is ionic due to the presence of magnesium (a metal) and phosphate (a non-metal), the bonds within the phosphate ion itself are covalent. The video also discusses the ionic charges of magnesium and phosphate ions, showing how they balance to form a stable compound. The phosphate ion is highlighted as a covalent structure due to its non-metal components.
