This question is not yet old enough to be eligible by my own rules, but I would like to revive this thread so I am nominating it anyway:
Why is an S-S bond stronger than an O-O bond?Why is an S-S bond stronger than an O-O bond?
I think this question is very intriguing and one might come by quite tempting easy explanations. In order to further understanding of chemical bonding a canonical answer would be really helpful. I am almost certain, that there are already reports about such investigations out there. However, I do not have the time to find it myself.
As for the user argument; Ina is very active on the site and has proven a good sport and he also asks quite interesting questions. While an answer is rewarding for everyone, I think he has supplied us with a solid foundation and hence really deserves some attention.
If you comment, I'll take it back.
