Homework Help: Stability of Highest Oxidation State

  1. Aug 22, 2008 #1
    1. The problem statement, all variables and given/known data

    Why does the stability of highest oxiation state decreases from group 13 to group 17?

    Ans: My book says, that with the increase in atomic number, difference in energies between ns and np orbitals increases. Is it right? If so then can u please explain what relation exists between the statements.

    It's better to consider this in terms of electron affinity. The energies between ns and np orbitals increases because of the increase in effective nuclear charge i.e. " it wants the electrons more " .
