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.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Solution
$E=-\frac{2 \pi^2 k^2 m_e^4}{n^2 h^2}$
where $n=$ principal quantum number which has only integral value, it follows that total energy is quantized.
