Chapter 7, Problem 7.69QE

(a)

Interpretation Introduction

Interpretation:

The order of increasing energy for $5p,2p,3d,2s,3p$ subshells in a multielectron atom has to be determined.

Concept Introduction:

Aufbau principle states that in a multielectron atom, orbital with lowest energy is occupied first by the electron that has to be filled. This filling of electrons results in a certain pattern known as electronic configuration.

According to the Aufbau principle, the order of increasing energy for orbital in a multielectron atom is as follows:

  $1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s$
