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

1. Principal quantum number ($n$) gives the size of the orbital.

2. Azimuthal quantum number ($l$) gives the shape of the orbital.

3. Magnetic quantum number ($m$) gives the orientation of the orbital.

4. Spin quantum number ($m_s$) gives the orientation of the spin of the electron.
