 Custom Search Lewis Dot of Sulfur Tetrafluoride SF4 S does not follow the octet rule. It will hold more than 8 electrons. Sulfur having valence electrons in the 3rd energy level, will also have access to the 3d sublevel, thus allowing for more than 8 electrons. SF4 is dsp3 hybridized and contains 1 lone pair and 4 bonding pairs of valence electrons around the sulfur. The VSEPR predicts the see-saw 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. ABOUT SF4- This species exists as a gas at standard conditions. It is a corrosive species that releases dangerous hydrogen fluoride upon exposure to water or moisture. Note Bond Angles
