Ionic Compounds and Their Properties

The video tutorial explains how to name and write the formula for the ionic compound KF, known as potassium fluoride. It begins by identifying KF as an ionic compound due to the presence of a metal and a non-metal. The tutorial then details the naming process for binary ionic compounds, highlighting the use of the periodic table to name the metal and modifying the non-metal's name to end in 'ide'. Finally, it covers the formula derivation by balancing the ionic charges of potassium and fluorine to achieve a net charge of zero.
