# Shielding of Electrons: Estimating Zeff

The shielding of electrons gives rise to an effective nuclear charge, Zeff, which explains why boron is larger than oxygen. Estimate the approximate Zeff 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
