Find the incorrect set of quantum number.

Correct answer: D. n=3, l=2, m=3, s=+1/2

  • A. n=2, l=1, m=0, s=1/ 2
  • B. n=4, l=3, m=1, s=+1/2
  • C. n=5, l=3, m=2, s=+1/2
  • D. n=3, l=2, m=3, s=+1/2

Explanation

If the angular momentum quantum number of an electron =3, which means (n-1) values are possible for l, so the possible values of l = 0,1,2. The possible values of m will be ± l that are -2,-1,0,1,2, and s will always be +1/2. The value of m will never be more than l, thus this is not a valid set of quantum numbers.

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.
