Question

Principal, azimuthal and magnetic quantum numbers are respectively related to

(a) shape, size and orientation

(b) size, shape and orientation

(c) size, orientation and shape

(d) none of these

Answer 1

Correct option \((b)\) size, shape and orientation
Explanation:
Principal quantum number \((n)\) represents the name, size and energy of the shell of the electron. \(n=1,2,3,4 \ldots \ldots\)

Azimuthal quantum number (l) describes the spatial distribution of electron cloud and angular momentum.
Magnetic quantum number \((\mathrm{m})\) describes the possible orientations of orbitals.
