What would be the Z eff for an electron in 1s, 2s or 2p occupied orbital (1s, 2s or 2p) in Sc?
Dear student, For a many electron atom EPE = -<Ze2/r >Here the brackets represent an average -- we must take an average because the electron does not remain at one fixed value of r .Earlier, we noted that Eorb = -Ze2/2 <1/r> These averages are dominated by contributions at SMALL r. When r is SMALL,(1/r) is LARGE; thus, the larger the fraction of its time an electron spends at SMALL r, the MORE NEGATIVE -Ze2/2 <1/r> will be,and the ELECTRON will be "BOUND" MORE TIGHTLY to the nucleus (i.e Eorb will be more NEGATIVE).
