Which quantum number provides information about the shape of an orbital?

Options

  1. ASpin quantum number
  2. BAzimuthal quantum number
  3. CMagnetic quantum number
  4. DPrincipal quantum number

Correct answer

B. Azimuthal quantum number

Step-by-step solution

The azimuthal quantum number is given the shape of the orbital. It is a quantum number for an atomic orbital that determines its orbital angular momentum and describes its shape. The azimuthal quantum number is the second of a set of quantum numbers representing an electron's unique quantum state. For example l   =   0 represent spherical orbital, l = 1 represent dumbbell shape orbital Hence, option B is the correct answer.
