AIIMS 2008 Chemistry Quantum Numbers Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 11

Assertion: The quantized energy of an electron is largely determined by its principal quantum number.

Reason: The principal quantum number n is a measure of the most probable distance of finding the electron around the nucleus.

A

Both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

Assertion is true but Reason is false.

D

Both Assertion and Reason are false.

Correct Answer

Option A

Detailed Explanation

E = \frac{2π^2k2k^2m_e}{n^2$$h^2} where n = principal quantum number which has only integral value, it follows that total energy is quantized.
