Question

Match List I with List II

List-I (Quantum Number)		List-II  (Information provided)
(A)	mI	(I)	Shape of orbital
(B)	ms	(II)	Size of orbital
(C)	I	(III)	Orientation of orbital
(D)	n	(IV)	Orientation of spin of electron

Choose the correct answer from the options given below:

• A. A-I, B-III, C-II, D-IV
• B. A-III, B-IV, C-I, D-II
• C. A-III, B-IV, C-II, D-I
• D. A-II, B-I, C-IV, D-III

Answer 1

The Correct Option is B

Match each quantum number with its provided information:

(A) m_l (Magnetic Quantum Number): Specifies the spatial orientation of an orbital, determining the number and orientation of orbitals within a subshell.

Therefore, (A) corresponds to (III) Orientation of orbital.

(B) m_s (Spin Quantum Number): Describes the intrinsic angular momentum (spin) of an electron and its orientation.

Therefore, (B) corresponds to (IV) Orientation of spin of electron.

(C) l (Azimuthal Quantum Number): Determines the shape of an orbital and its subshell, with possible values from 0 to n-1.

Therefore, (C) corresponds to (I) Shape of orbital.

(D) n (Principal Quantum Number): Dictates the size and energy level of an orbital, taking positive integer values (1, 2, 3, ...).

Therefore, (D) corresponds to (II) Size of orbital.

Matching Summary:

(A) - (III)

(B) - (IV)

(C) - (I)

(D) - (II)
