The Chemistry Misconception That Just Won't Go Away | What The FOOF?

One way to rationalize bonding interactions is that atoms will gain and lose electrons in order to reach a stable configuration with eight valence electrons. This is what is known as the octet rule. However, some molecules appear to violate this rule. For example sulfur hexafluoride, which looks to have 12 electrons around the central sulfur atom. The chemist Linus Pauling proposed the idea that this expanded octet was possible through the use of sulfur's vacant d orbitals. And although this idea has since been discredited, it still often shows up in classrooms and textbooks 75 years later.
