Question

The azimuthal quantum number indicates the angular momentum of an electron.

• A. True
• B. False

Answer 1

The correct option is A True

1. Quantum numbers are used to describe the position and energy of an electron in the atom.
2. There are four quantum numbers: Principal quantum number ($\mathrm{n}$), azimuthal quantum number ($\mathcal{l}$), magnetic quantum number (${\mathrm{m}}_{\mathrm{l}}$) and spin quantum number (${\mathrm{m}}_{\mathrm{s}}$).
3. Azimuthal quantum number ($\mathcal{l}$):

1. It tells about the shape of the orbital or subshell of the electron.
2. It also indicates the angular momentum of an electron.
3. It tells whether the orbital is s,p,d or f.

Hence, the given statement is TRUE.
