Ionic Compounds and Their Properties

The video tutorial explains how to name the ionic compound CaF2, known as calcium fluoride. It begins by identifying CaF2 as an ionic compound composed of a metal and a non-metal. The tutorial then details the steps to name the compound: writing 'calcium' for Ca and modifying 'fluorine' to 'fluoride' by changing the ending. It also covers how to derive the formula from the name, explaining the charges of calcium and fluoride ions and how they balance to form CaF2. The video concludes with a summary of the naming and formula process.
