Question

The orientation of an atomic orbital is governed by:

• A. Azimuthal quantum number
• B. Spin quantum number
• C. Magnetic quantum number
• D. Principal quantum number

Answer 1

The correct option is C Magnetic quantum number

The principal quantum number represents the name, size and energy of the shell to which the electron belongs.

The azimuthal quantum number describes the spatial distribution of electron cloud and angular momentum.

The magnetic quantum number describes the orientation or distribution of electron cloud.

The spin quantum number represents the direction of electron spin around its own axis.

Hence, option C is correct.
