An electronic transition in hydrogen atom results in the formation of \(\mathrm{H}_\alpha\) line of hydrogen in Lyman series, the energies associated with the electron in each of the orbits involved in the transition (in kcal \(\mathrm{mol}^{-1}\) ) are
- A \(-313.6,-34.84\)
- B \(-313.6,-78.4\)
- C \(-78.4,-34.84\)
- D \(-78.4,-19.6\)
Answer & Solution
Correct Answer
(B) \(-313.6,-78.4\)
Step-by-step Solution
Detailed explanation
Energy of an electron in \(n^{\text {th }}\) orbit, \[ E_n=-\frac{2 \pi^2 k^2 m Z^2 e^4}{n^2 h^2} \] On substituting the values of \(k, m, e\) and \(h\), we get…
