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