The wavelength corresponding to electronic transition between two orbits of hydrogen atom is \(912 Å\). The wavelength (in \(Å\) ) for the same electronic transition in \(\mathrm{Li}^{2+}\) is
- A 101.3
- B 202.6
- C 303.9
- D 50.65
Answer & Solution
Correct Answer
(A) 101.3
Step-by-step Solution
Detailed explanation
\(\because E=\frac{h c}{\lambda}\), i.e. \(E \alpha \frac{1}{\lambda}\) and \(E \alpha \frac{Z^2}{n^2}\) For same value of (n) \(E \alpha Z^2\) Thus, \(E \alpha Z^2 \alpha \frac{1}{\lambda}\) where, \(E=\) energy, \(\lambda=\) wavelength \(Z=\) atomic number Therefore,…
