Chapter 6.8, Problem 1PPB

Interpretation Introduction

Interpretation:

The absence of $2d$ subshell using quantum numbers is to be explained.

Concept introduction:

Principal Quantum Number $\left(n\right)$ refers to the size of an atom’s orbital. The larger the value of $\left(n\right)$, the greater is the size of orbital.

Angular Momentum Quantum Number $\left(l\right)$ describes the shape of an atom’s orbital. The values of $\left(l\right)$ are integers. Its values range from $0$ to $\left(n-1\right)$.

Magnetic Quantum Number $\left(m_l\right)$ describes the orientation of orbital in space with the help of integral values, and so, it depends on the value of $\left(l\right)$. For a value of $\left(l\right)$, there will be $\left(2l+1\right)$ number of integral values of $\left(m_l\right)$.
