Barium Chloride and Ionic Compounds

The video tutorial explains how to determine if barium chloride (BaCl2) is ionic or covalent. It presents two methods: examining the periodic table to identify the presence of a metal and a non-metal, and calculating the electronegativity difference between barium and chlorine. The tutorial concludes that BaCl2 is an ionic compound due to the significant electronegativity difference and the combination of a metal and a non-metal.
