Assertion : Only principal quantum numbe...

Assertion : Only principal quantum number determines the energy of an electron in an orbital of Na atom.
Reason : For one electron system, the expression of energy is quite different from that obtained in Bohr's theory. : If both (A) and (R) are correct and (R) is the correct explanation of(A)., If both (A) and (R) are correçt, but (R) is not the correct explanation of (A)., If (A) is correct, but (R) is incorrect., If both (A) and (R) are incorrect.

A

If both (A) and (R) are correct and (R) is the correct explanation of(A).

B

If both (A) and (R) are correçt, but (R) is not the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
D
To find the energy of an electron in an orbital, both principal and azimuthal quantum numbers are required. For one electron system, the expression of energy is same as that obtained in Bohr.s theory.
