Quote of the day
I have seen many phases of life; I have moved in imperial circles, I have been a Minister of State; but if I had to live my life again, I would always remain in my laboratory, for the greatest joy of my life has been to accomplish original scientific work, and, next to that, to lecture to a set of intelligent students.
Jean-Baptiste-André Dumas, 1800-1884

- 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...
