Chapter 1, Problem 1D.25E

(a)

Interpretation Introduction

Interpretation:

The given subshell $2d$ can exist in an atom or not has to be explained.

Concept Introduction:

There are four set of quantum numbers present for explaining the distribution of electron density in an atom.  They are principal quantum number, angular momentum quantum number, magnetic quantum number and spin quantum number.

    $\begin{array}{cccc}\text{Name}& \text{Symbol}& \text{Values}& \text{Specifies}\\ \text{Principal}& \text{n}& \text{1,2,}\mathrm{...}& \text{shell}\\ \text{angular momentum}& \text{l}& \text{0,1,}\mathrm{...}\text{n-1}& \begin{array}{l}\text{subshell:}\\ \text{l}\text{=}\text{0,1,2,3,4}\mathrm{...}\\ \text{s,p,d,f,g}\mathrm{...}\end{array}\\ \text{magnetic}& {\text{m}}_{\text{l}}& \text{l,l-1,}\mathrm{...}\text{,-1}& \text{orbitals}\text{of}\text{shell}\\ \text{spin}& {\text{m}}_{\text{s}}& \text{+}\frac{\text{1}}{\text{2}}\text{,-}\frac{\text{1}}{\text{2}}& \text{spin}\text{state}\end{array}$

For a given value of $\text{n,}$ there will be $\text{n}$ different values for $l.$  And in the case of magnetic quantum number, there will be $\left(2l+1\right)$ different values of $m_l$ present for each values of $l.$
