Solutions

Chapter 6, Problem 29PS
Interpretation Introduction

Interpretation: The possible set of quantum number for an excited H atom whose electron is in 4p orbital has to be identified.

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.

For an orbital ns, the principal quantum number is n

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.
