Textbook Problem

Which of the following represent valid sets of quantum numbers? For a set is invalid, explain briefly why it is not correct.

  1. (a) n = 3, ℓ = 3, mℓ = 0
  2. (b) n = 2, ℓ = 1, mℓ = 0
  3. (c) n = 6, ℓ = 5, mℓ = ‒1
  4. (d) n = 4, ℓ = 3, mℓ = ‒4

(a)

Interpretation Introduction

Interpretation: The given set is whether valid or invalid sets of quantum numbers should be identified and the reason should be briefly explained if it is an invalid set of quantum numbers.

Concept introduction:

Quantum numbers are numbers, which explains the existence and the behavior of electron in an atom.

  1. a) Principle quantum number is represented by n and this number describes the energy of the orbital and the size of an atom.
  2. b) Angular momentum quantum number (or azimuthal quantum number) is represented by l and this number indicates the shape of the orbitals.
  3. c) Magnetic quantum number is represented by ml and this number indicates the orientation of the orbital.
  4. d) Spin quantum number is represented by ms and this number indicates the spin of the electron.

The principal quantum number and number of subshells are same in a shell.

The values of l when the principal quantum number is n are from 0 to (n1). Each l value indicates subshell.

The values of ml when the orbital angular quantum number is l are from l to +l.

Explanation

Given,

  n=3,l=3,ml=0

The values of l when the principal quantum number is n are from 0 to (n1). Each value indicates subshell.

The values of ml when the orbital angular quantum number is l are from l to +l
