Ionic Compounds and Their Properties

The video tutorial explains how to name the ionic compound KBr, known as potassium bromide. It begins by identifying KBr as a binary ionic compound, formed by the bonding of a metal (potassium) and a non-metal (bromine). The tutorial outlines the naming convention for such compounds: the metal name is written first, followed by the non-metal with its ending changed to 'ide'. The video also covers the ionic charges of potassium and bromide ions, explaining how they balance each other to form a neutral compound.
