Here's my favourite warning, can you guess what it is?

[–] [email protected] 1 points 4 days ago* (last edited 4 days ago) (2 children)

NFPA 704 Color Diamond

Possibly some type of Bromine or Chlorine compound.

Chlorine trifluoride, so yeah not too far off

My brain is short circuiting imagining how that is created and where the electrons are going. I miss chem and o-chem classes. That was over 10 years ago. Does chlorine only have 7 valence electrons? How can it bind with more than one other atom? What am I forgetting?
