Ncert Exercises & Solutions

Match the quantum numbers with the information provided by them:

	Quantum number		Information provided
A.	Principal quantum number	1.	Orientation of the orbital
B.	Azimuthal quantum number	2.	Energy and size of orbital
C.	Magnetic quantum number	3.	Spin of electron
D.	Spin quantum number	4.	Shape of the orbital

Codes:

	A	B	C	D
1.	2	4	1	3
2.	1	2	3	4
3.	1	4	3	2
4.	4	1	3	2

Hint: Orientation of the orbital is represented by m values.

Explanation:

A. Principal quantum number is the most important quantum number as it determines the size and to large extent the energy of the orbital.

B. Azimuthal quantum number determines the angular momentum of the electron and defines the three-dimensional shape of the orbital.

C. Magnetic quantum number gives information about the spatial orientation of orbitals with respect to a standard set of coordinate axes.

D. Spin quantum number arises from the spectral evidence that an electron in its motion around the nucleus in an orbit also rotates or spin about its own axis.
