Question

Use a simplified model for electronic structure where all electrons of a given “n” value are assumed to have the same average energies and to reside the same distance from the nucleus in answering this question: What is the effective nuclear charge (Zeff) felt by the valence electrons of C?

Answer 1

• Effective nuclear charge is that the charge felt by the valence electrons when you have got taken into consideration the quantity of protecting electrons that encompass the core or nucleus.

• The expansion in the atomic charge is offset by the increment in protecting electrons and the successful atomic charge remains practically the equivalent. In carbon the 4 valence electrons in the furthest shell feel a +6 charge encompassed by two protecting electrons for a +4 compelling atomic charge.

• Therefore, the effective nuclear charge felt by the valence electrons of Carbon (C) is 4.
