In the experimentally observed Zeff values for the 2p elements, we find that the increase in the Zeff for a 2p electron is slightly smaller between N and O (ΔZeff ≈ 0.62) than between C and N (ΔZeff ≈ 0.69). Which of the following is not a reason for the differences in the ΔZeff values?

MCQS on the chemistry, properties, and reactivity of metal-containing compounds. Topics include atomic structure and electron configurations, bonding theories, ionic bonding, ionic solids and packing structures, band theory, alloys, semiconductors, and superconductors, inorganic acids and bases, and the properties and compounds of Group 1-7 elements.
