Ionic Compounds and Carbonate Ions

The video explores whether sodium carbonate (Na2CO3) is ionic or covalent. It identifies sodium as a metal and carbon and oxygen as non-metals, leading to the conclusion that sodium carbonate is an ionic compound. The video explains the charges on sodium and carbonate ions, highlighting the ionic bonds between sodium and the carbonate ion, and the covalent bonds within the carbonate ion itself. Ultimately, sodium carbonate is classified as an ionic compound due to the presence of ions.
