Ionic Compounds and Lithium Ions

The video tutorial explains how to name the ionic compound Li2O, known as lithium oxide. It begins by identifying lithium as a metal and oxygen as a non-metal, forming an ionic compound. The tutorial outlines the steps to name the metal and non-metal, replacing the ending of the non-metal with 'ide' to form 'lithium oxide'. It also covers how to write the chemical formula from the name, considering the charges of lithium and oxygen ions to balance the compound.
