Ionic Compounds and Their Properties

The video tutorial explains how to write the formula for strontium bromide, an ionic compound. It begins by identifying strontium as a metal and bromine as a non-metal, highlighting their positions on the periodic table and their respective ionic charges. The tutorial then demonstrates how to balance these charges to achieve a net charge of zero, resulting in the formula SrBr2. The video concludes with a brief summary of the process.
