Barium Nitrate: Properties and Bonds

The video explores whether barium nitrate (Ba(NO3)2) is ionic or covalent. It explains that barium is a metal, while nitrogen and oxygen are non-metals. When metals bond with non-metals, they form ionic compounds. Barium has a 2+ charge, and the nitrate ion (NO3) has a 1- charge. The charges balance out, resulting in an ionic bond between barium and nitrate ions. However, within the nitrate ion, nitrogen and oxygen form covalent bonds. Overall, barium nitrate is an ionic compound due to the ionic bond between barium and nitrate ions.
