For sets of values of quantum numbers (n, l, m and s) are given below. Which of these does not provide a permissible solution of the wave equation?

Correct answer: E. Both B and C

  • A. 3, 2, -2, 1/2
  • B. 3, 3, 1, -1/2
  • C. 0, 3, 1, -1/2
  • D. 3, 1, 1, -1/2
  • E. Both B and C

Explanation

The correct answer is Option E both B and C : 3, 3, 1, -1/2. According to the rules of quantum numbers, the azimuthal quantum number l must be in the range 0 to n-1. Therefore, l=3 is not permissible when n=3, as l should be less than n.In Option A and D, the values of l and m are within permissible ranges for n=3. In Option C, the principal quantum number n cannot be zero, making it invalid.

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
