Magnetic quantum number values for the d-subshell are:

Correct answer: C. 5

  • A. 2
  • B. 3
  • C. 5
  • D. 7

Explanation

The correct option is c) 5. The magnetic quantum number (m) represents the orientation of an orbital within a subshell. For the d-subshell, which has an azimuthal quantum number (ℓ) of 2, the possible values of the magnetic quantum number range from -2 to +2. Now let's examine why the other options are incorrect: a) 2: This option is incorrect because the total value of the magnetic quantum number (m) for the d-subshell is 5, not 2. b) 3: This option is incorrect because the total value of the magnetic quantum number (m) for the d-subshell is 5, not 3. d) 7: This option is incorrect because the total value of the magnetic quantum number (m) for the d-subshell is 5, not 7. Therefore, the correct answer is c) 5, as it correctly represents the range of values for the magnetic quantum number in the d-subshell (-2, -1, 0, 1, 2).

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.
