As the solo chemistry teacher at an international school, introducing the IB, this site literally "saved my skin" -never felt alone and a wonderful resource. Highly recommended

Quote of the day
Men will gather knowledge no matter what the consequences. Science will go on whether we are pessimistic or optimistic, as I am. More interesting discoveries than we can imagine will be made, and I am awaiting them, full of curiosity and enthusiasm.
(Linus Carl Pauling, 1901-1994)

- Hi John, You make a valid point (to Richard?) about HF and BF3 - although fluorine with an electronegativity value of 4 is always a problem with the ~ 1.8 rule of thumb - but I'm still not convinced that triangular bonding...
- Hello Omar, I'm a chemist, not a physicist, and the question is hypothetical as absolute zero can never be reached. As I understand it particles at absolute zero would not possess translational or vibrational kinetic energy. All particles...
- Richard,Interesting points in the Pause for Thought. The lead chloride examples are particularly interesting. I do find the Triangle most useful for compounds involving Fluorine. If you use the delta EN> 1.8 rule, then students...
