Barium Sulfate Bonding Concepts

The video explores whether barium sulfate (BaSO4) is ionic or covalent. It concludes that BaSO4 is an ionic compound due to the presence of a metal (barium) and non-metals (sulfur and oxygen). The video explains that barium has a 2+ charge and the sulfate ion has a 2- charge, resulting in a net charge of zero, forming an ionic bond. The sulfate ion itself has covalent bonds between sulfur and oxygen. Overall, BaSO4 is ionic, but the sulfate ion's internal bonds are covalent.
