Chemical Bonds and Ionic Compounds

The video explores whether calcium carbonate (CaCO3) is ionic or covalent. It explains that the compound is overall ionic due to the interaction between calcium (a metal) and the carbonate ion (a non-metal). The carbonate ion itself contains covalent bonds between carbon and oxygen. The video also discusses the ionic charges of calcium and carbonate, which lead to the formation of ionic bonds. In summary, while the carbonate ion has covalent bonds, the overall compound is ionic.
