What does Ek Mean by this "For representative elements the principal quantum number for e- in the outer most shells is given by the period in the periodic table. The principal quantum number for the transition metals lags one shell behind the period, and for the lanthanides and actinides lags 2 shells behind the period" (page 16).
Isn't the principal quantum number for transition metals also their period number? For instance, Fe = [Ar] 3d^6 4s^2. So wouldn't the principal quantum number be 4?
thanks!
