Valence Electrons in SeF6

The video explains the Lewis structure for SeF6, detailing the valence electrons of Selenium and Fluorine. Selenium, being less electronegative, is placed at the center with six Fluorines around it. The video demonstrates how to use 48 valence electrons to form bonds and complete the octets for Fluorine. It also explains why Selenium can have more than eight valence electrons due to its position in period four of the periodic table.
