Estimate the approximate valence electron of boron and oxygen?
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 valence electron of boron and oxygen, respectively?A. +5 and +8B. +3 and +6C. +5 and +6D. +3 and +8E. +1 and +4
