Naming and Properties of Ammonium Bromide

The video tutorial explains how to name the compound NH4Br, known as ammonium bromide. It begins by identifying NH4 as the ammonium ion with a +1 charge and bromine as having a -1 charge. The tutorial details the naming process, emphasizing the importance of recognizing the ammonium ion and modifying bromine to bromide. It also covers the formation of ionic bonds between the ammonium and bromide ions, resulting in an ionic compound. Finally, the video demonstrates how to derive the formula NH4Br by balancing the charges to achieve a net charge of zero.
