We estimated the effective nuclear charge on beryllium’s
valence electrons to be slightly greater than 2+. What
would a similar process predict for the effective nuclear charge
on boron’s valence electrons? Would you expect the effective
nuclear charge to be different for boron’s 2s electrons compared
to its 2p electron? How so? (*Hint:* Consider the shape of the 2p orbital compared to that of the 2s orbital.)

The effective nuclear charge experienced by an electron in an atom can be estimated by the actual nuclear charge (Z) minus the charge shielded by other electrons (S):
