Chapter 5, Problem 5.85SP

Interpretation Introduction

Interpretation:

The electron shielding in multi electron atoms give rise to energy difference among the order is $\text{3s}\text{}>\text{3p}\text{}>\text{3d}$.

Concept Introduction:

An electron in an $\text{3s}\text{}$ orbital can enter nearer to the core than an electron in a $\text{3p}$ orbital can and feels to a lesser degree a protecting impact from alternate electrons. For the most part of estimation of guideline in a quantum number $\text{n}$ , a lower estimation of corresponds to the higher estimation vitality for the orbital.
