Naming and Properties of Ionic Compounds

The video tutorial explains how to name the ionic compound K2O. It begins by identifying K2O as a binary ionic compound composed of potassium and oxygen. The naming process involves writing the metal name as it appears on the periodic table and modifying the non-metal name by replacing its ending with 'ide'. The tutorial also covers the ionic charges of potassium and oxygen, explaining how to balance them to form the compound. The video concludes with a brief summary.
