Barium Hydroxide Bonding Concepts

The video explores whether barium hydroxide (BaOH2) is ionic or covalent. It begins by examining the bond between barium, a metal, and the hydroxide group, a polyatomic ion. Using the periodic table, it identifies barium as a metal and oxygen and hydrogen as non-metals, leading to the conclusion that barium hydroxide is an ionic compound. The video explains the ionic charge of barium and hydroxide, showing how they balance to form an ionic bond. It also discusses the covalent bonds within the hydroxide ion, emphasizing that the overall compound is ionic.
