Lewis Structure of SeBr2

The video tutorial explains how to write the Lewis structure for SeBr2. It begins by counting the valence electrons for selenium and bromine, totaling 20 electrons. Selenium is placed at the center with bromine atoms on either side. Electron pairs are added to form bonds, and the octets for bromine are completed. Finally, the remaining electrons are used to complete the octet for selenium, resulting in a complete Lewis structure for SeBr2. The tutorial concludes with a sign-off from Dr. B.
