se Home Chapter 7 roblem 7.80 21 of 29 Part B How would you modity Slater's rules to adjust for the difference in electronic penetration of the nucleus for the 2s and 2p orbitals? Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Reset Help 0.35 1. Slater's rules provide a method for calculating the shielding, S, and Zeff experienced by a 0.85 particular electron in an atom. Slater assigns a shielding value of to electrons with the same n-value, assuming that s and p electrons shield each other to the same extent. However 1.0 because electrons have a finite probability of being very close to the nucleus, they shield electrons shield them. To account for this electrons more than P difference, assign a slightly larger shielding value to electrons and a slightly smaller shielding value to the electrons. This will produce a slightly greater S and smaller Zff for electrons than for electrons with the same nvalue.

Answer 1

This is a question based on factual information rather than logic.

The answers in the order of the blanks are:

0.35

s

p

p

s

p

s

p

This accounts to the fact that the penetrative power of s-orbitals is greater than that of p-orbitals and hence electrons in s-orbitals shield more effectively than that of electrons in p-orbital.
