Lewis Dot of Iodine Pentafluoride
I does not follow the octet rule. It will hold more than 8 electrons.
Iodine having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons. IF5 is d2sp3 hybridized and contains 1 lone pair and 5 bonding pairs of valence electrons around the Iodine. The VSEPR predicts the square pyramidal 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.
