Chapter 8, Problem 8A.11AE

(i)

Interpretation Introduction

Interpretation:

The orbital angular momentum of an electron in $\text{1s}$ orbital has to be calculated as a multiple of $\hslash$.  The numbers of angular and radial nodes in $\text{1s}$ orbital have to be calculated.

Concept introduction:

Orbital angular momentum is the component of angular momentum of an electron which arises due to motion of an electron in the orbit.  The positions where the probability of locating an electron is zero are termed as nodes.

(ii)

Interpretation Introduction

Interpretation:

The orbital angular momentum of an electron in $\text{3s}$ orbital has to be calculated as a multiple of $\hslash$.  The numbers of angular and radial nodes in $\text{3s}$ orbital have to be calculated.

Concept introduction:

Orbital angular momentum is the component of angular momentum of an electron which arises due to motion of an electron in the orbit.  The positions where the probability of locating an electron is zero are termed as nodes.

(iii)

Interpretation Introduction

Interpretation:

The orbital angular momentum of an electron in $\text{3d}$ orbital has to be calculated as a multiple of $\hslash$.  The numbers of angular and radial nodes in $\text{3d}$ orbital have to be calculated.

Concept introduction:

Orbital angular momentum is the component of angular momentum of an electron which arises due to motion of an electron in the orbit.  The positions where the probability of locating an electron is zero are termed as nodes.
