SF6, ClF5, and XeF4 are three compounds whose central atoms do not follow the octet rule. Draw Lewis structures for these compounds.
To draw the Lewis structure of each of the compound, we must first determine how many valence electrons each of them have so we can use those electrons to form bonds or distribute them as lone pairs on the atoms.
SF6
• S → Group 6A → 6 valence e-
• F→ Group 7A → 7 valence e- x 6
• Total valence e- = 48 e-
