Chapter 2, Problem 27Q

Interpretation Introduction

Interpretation: The significance of sign indication in representing $\text{p}$ and $\text{d}$ atomic orbitals is to be explained.

Concept introduction: The signs indicate the lobes of atomic orbital. It is just a mathematical representation of displacement of waves. It does not represent any kind of charges.

To determine: The significane of ‘+’ and ‘-’  signs indicated in figure 2-15 and 2-17 which represents $\text{p}$ and $\text{d}$ atomic orbitals.
