Chapter 2.5, Problem 2.23P

(a)

Interpretation Introduction

Interpretation:

The maximum number of electrons in an $\text{2p}$ orbital has to be given.

(b)

Interpretation Introduction

Interpretation:

The maximum number of electrons second energy level has to be given.

Concept Introduction:

The maximum number of electrons in the energy level can be calculated using the formula,

  $\text{Maximum}\text{number}\text{of}{\text{electrons=2n}}^{\text{2}}$

Where n is the energy of level.

(c)

Interpretation Introduction

Interpretation:

The maximum number of electrons in $\text{3s}$ orbital has to be given.

(d)

Interpretation Introduction

Interpretation:

The maximum number of electrons third energy level has to be given

Concept Introduction:

Refer to part (b).
