Electronic configurations follow from the principle quantumnumbers n, l, m, and s. What is the relationship with n and theperiodic table? What is the relationship with n and the number ofvalance electrons? The ‘l ’ quantum number designates the type oforbital. What is an orbital? Do electrons have to stay in theirdesignated orbital? The ‘m’ quantum number gives the degeneracy ofthe orbital type. Is there a difference in the px and py orbitals?Why does the spinning of the two electrons sharing an orbital haveto be opposite. Are electrons really spinning?
