Chapter 2, Problem 53P

(a)

Interpretation Introduction

Interpretation:

Based on principles of writing electronic configuration, write the correct condensed electronic ground state configuration for

Rb

Concept introduction:

The electronic configuration is based on the following rules

1. Pauli’s exclusion principle (no two electrons in the same element can have all the four quantum numbers same)
2. Hund’s rule of multiplicity ( the electrons are first filled in all the degenerate orbitals and then pairing starts)
3. Pauli’s exclusion principle (the electrons are filled based on the energy of orbitals)

(b)

Interpretation Introduction

Interpretation:

Based on principles of writing electronic configuration, write the correct condensed electronic ground state configuration for

Sr
