The inert-pair effect is sometimes used to explain the tendency of heavier members of Group 3A (13) to exhibit +1 and +3 oxidation states. What does the inert-pair effect reference? [Hint: Consider the valence electron configuration for Group 3A (13) elements.]
Look in Appendix D and compare the electron configurations shown there with the fusion enthalpies for the metals shown in Table 9.7. Is there any correlation between these configurations and this property? Does strength of attraction among metal atoms correlate with number of valence electrons? Explain your answers.
