Valence Electrons and Bonding in Fluorine

Dr. B explains how to draw the Lewis structure for F2, Fluorine gas. He starts by identifying Fluorine's group on the periodic table to determine its valence electrons. With two Fluorine atoms, the total is 14 valence electrons. He demonstrates how to bond the atoms and distribute electrons to satisfy the octet rule. Finally, he shows how to represent the structure with a single line as a structural formula.
