Question

The quantum number which explains about the spacial orientation of orbitals is

• A. n
• B. l
• C. m_l
• D. m_s

Answer 1

The Correct Option is C

To solve this question, we need to identify which quantum number describes the spatial orientation of orbitals.

1. Types of Quantum Numbers:
- Principal quantum number (n): Indicates the energy level or shell.
- Azimuthal quantum number (ℓ): Describes the shape of the orbital.
- Magnetic quantum number (m_ℓ): Describes the spatial orientation of orbitals in a magnetic field.
- Spin quantum number (m_s): Represents the spin of the electron (either +½ or –½).

2. Correct Quantum Number for Spatial Orientation:
The magnetic quantum number (m_ℓ) defines the orientation of orbitals in space around the nucleus.

Final Answer:
Option (C) m_ℓ is correct.
