Ionic and Covalent Bonding Concepts

The video explores whether sodium nitrite (NaNO2) is ionic or covalent. It explains that sodium nitrite is an ionic compound due to the presence of a metal (sodium) and non-metals (nitrogen and oxygen). The sodium ion has a positive charge, while the nitrite ion has a negative charge, forming an ionic bond. Within the nitrite ion, the bonds between nitrogen and oxygen are covalent. The video concludes that while the overall compound is ionic, it contains covalent bonds within the nitrite ion.
