SF2 Lewis Structure and Valence Electrons

Dr. B explains how to draw the Lewis structure for SF2. Sulfur has six valence electrons, and each fluorine has seven, totaling 20 valence electrons. Sulfur is placed at the center with fluorines on either side. Electrons are distributed to form bonds and complete octets. The formal charges are checked to confirm the best structure, which results in zero formal charges, indicating stability.
