Effective nuclear charge (Z_eff) felt by an electron in 2p orbital of nitrogen, given Z = 7, screening constant σ ≈ 3.25:
A~7
B~1.85
C~3.75
D~5.75
Answer & Solution
Correct answer: C. ~3.75
Z_eff = Z - σ = 7 - 3.25 ≈ 3.75. Slater's rules give the approximate effective charge after accounting for shielding by inner electrons.
