Ionic Compounds and Polyatomic Ions

The video tutorial explains how to name the compound Na2CO3, known as sodium carbonate. It begins by identifying sodium as the metal component and discusses its charge. The tutorial then explains the concept of charge balancing in ionic compounds, introducing polyatomic ions like CO3 2-. It demonstrates how to use the common ion table to identify the carbonate ion and finalize the compound's name. The video concludes with a call to action for further practice on naming and writing formulas.
