Problem 25QP

The electron configuration of C is 1s22s22p2 (a) If each core electron (that is. the 1s electrons) were totally effective in shielding the valence electrons (that is. the 2s and2p electrons) from the nucleus and the valcncc electrons did not shield one another, what would be the shielding constant (σ) and the effective nuclear charge (Zeff) for the 2s and 2p electrons? (b) In reality, the shielding constants for the 2s and 2p electrons in C are slightly different. They are 2.78 and 2.86, respectively. Calculate Zeff for these electrons, and explain the differences from the values you dctcniiincd in part (a).
