Chemical Compounds and Elements

The video tutorial explains how to write the chemical formula for tin(II) sulfide. It begins by identifying the element symbols for tin (Sn) and sulfur (S) from the periodic table. Tin is noted as a transition metal with a 2+ ionic charge, while sulfur, in group 16, has a 2- ionic charge. The tutorial demonstrates how these charges combine to form an ionic compound, resulting in the formula SnS. The video concludes with a brief thank you from Dr. B.
