1. The problem statement, all variables and given/known data How can I draw a Lewis dot structure for octathiocane (S8) which is non-cyclic, net neutral, and which does not violate the octet rule? 2. Relevant equations None. 3. The attempt at a solution First, I tried drawing a straight chain molecule, but the two terminal sulfurs each have a negative charge, giving a net negative charge overall. I then tried pushing an electron pair from one of the terminal sulfurs inwards, which solves the charge issue but makes the penultimate sulfur on one side violate the octet rule... I'm stumped. Any advice?
