Properties and Composition of MgCO3

The video tutorial explains how to name the compound MgCO3, known as magnesium carbonate. It begins by identifying the components: magnesium, a metal, and the carbonate ion, a polyatomic ion. The tutorial outlines the process of naming ionic compounds by first naming the metal, magnesium, followed by the polyatomic ion, carbonate. It also discusses the ionic charges involved, with magnesium having a 2+ charge and carbonate having a 2- charge, resulting in a neutral compound. The video concludes with a summary of the naming process.
