# All resonance structures of the hydrogen molecule

This answer written by Jan says that "a professor of mine claimed to have drawn some 18 (or was it 80?) different resonance Lewis structures."

Please reproduce those resonance structures of the hydrogen molecule.

If nobody is able to come up with that many, the answer with the most resonance structures would be accepted.

• I'm not sure if Jan's anecdote may have been a throwaway comment. Given the two electrons present its hard to imagine 4 combinations let alone 80. In any case. I like the challenge. May the odds be ever in your favour @Jan Sep 4, 2016 at 1:19
• @NotWoodward considering the three regions created by a hydrogen molecule there are already 6: 2+0+0, 0+2+0 (the usual one), 0+0+2, 1+1+0, 1+0+1, 0+1+1.

• @Mithoron I did not mean to challenge Jan's professor?

• For reference: The professor in question was Professor Klapötke from the LMU Munich.

• $\ce{H:H}$ (the usual one)
• $\ce{:H- H+}$
• $\ce{H+ H:^-}$
• $\ce{*H*H}$
• $\ce{H*H*}$
• $\ce{*H H*}$
• Come on, people. What's that even supposed to mean? Well, if we are just playing with dots, here are a few more: $\rm{\dot H\dot H}$, $\rm{H\ddot H}$, $\rm{\ddot HH}$, $\rm{\dot H\mathop{H}\limits_{.}}$. Nov 3, 2016 at 8:49
