    Ah yes, I think I dated C2N14 in college. To be fair I probably shouldn't have put her in a spectrometer.

      It's not Sulfur (S). It's Antimony (Sb).

    This term is not a real chemical name. The blogger Derek Lowe made up this term as a joke when referring to "1-diazidocarbamoyl-5-azidotetrazole". The joke name azidoazide azide has, however, been used since then, sometimes jokingly in imitation of Lowe, and sometimes apparently without realization of the joke origins of the name

    *Chlorine trifluoride fires are more than TWICE as hot as a magnesium fire!*
    Magnesium fires burn at 1110°C (2030°F), chlorine trifluoride burns at around 2400°C (4352°F).

    I just watched a video about dimethylmercury killing a woman scientist screwing with it, and now you talk about dimethylcadmium. Is it really worse than dimethylmercury? Because that stuff sounded about as bad as it could be. She died a horrible death after supposedly (and I think this part is a lie she said to avoid admitting she was being sloppy, because the amount she absorbed is too high to be consistent with her story) dropping two drops of it on.... her latex gloves, not on her skin.

      It's formed in a solution where it can't explode, once it's removed from solution things get dangerous.
