It takes less energy to dissociate a diatomic fluorine molecule than a diatomic oxygen molecule (in fact, less than one-third as much). Why is it easier to dissociate fluorine?
Because it has less number of covalent bonds.
Dissociation energy is a measure of the strength of a chemical bond and is defined as the energy needed to break the bond.
It is easy to dissociate fluorine molecules than to dissociate oxygen molecule because fluorine molecule has only one covalent bond but oxygen has two covalent bonds. It requires more energy to break two covalent bonds than one.
Hence, it is easier to dissociate fluorine.
Question: From the qualitative shapes of the interatomic potential energies in Fig. 10.21, would you expect the vibrational level in the excited electronic state to be spaced the same. Farther apart, or closer together than those in the lower energy electronic state? Explain what about the rotational levels?
Question: - A semimetal (e.g., antimony, bismuth) is a material in which electrons would fill states to the top of a band the valence band--except for the fact that the top of this band overlaps very slightly with the bottom of the next higher band. Explain why such a material, unlike the "real" metal copper, will have true positive charge carriers and equal numbers of negative ones, even at zero temperature.
