Question:

The shielding of electrons gives rise to an effective nuclear charge, {eq}Z_{eff} {/eq}, which explains why boron is larger than oxygen. Estimate the approximate {eq}Z_{eff} {/eq} felt by a valence electron of boron and oxygen, respectively.

(a) +5 and +8

(b) +3 and +6

(c) +5 and +6

(d) +3 and +8

(e) +1 and +4

Effective Nuclear Charge:

It is related with the shielding of electrons. Count of inner shell electrons and protons helps us in evaluating this nuclear charge.

{eq}{{\rm{Z}}_{{\rm{eff}}}}{\rm{ = Z - S}} {/eq}
