Lewis Dot of Xenon Difluoride
Xe does not follow the octet rule. It actually bonds. It will hold more than 8 electrons.
Xenon having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons. XeF2 is dsp3 hybridized and contains 3 lone pair and 2 bonding pairs of valence electrons around the Xenon. The VSEPR predicts the linear shape.
Elements in the first 2 periods of the Periodic Table do not have access to the d sublevel and must adhere to the octet (or duet H and He) rule.
