Short Answer

Expert verified

$λ_{32} = 10.26 nm; λ_{42} = 7.6 nm; λ_{52} = 6.79 nm$

Step by step solution

Step: 1 Given information

The given hydric lie are $O^{- 7}$

Step: 2 Calculation

We can begin by expressing our energy levels as follows:

$E_{n} = - \frac{13.6 Z^{2} (eV)}{n^{2}} E_{3} - E_{2} = - 13.6 Z^{2} (eV) \cdot (\frac{1}{3^{2}} - \frac{1}{2^{2}})$ $E_{3} - E_{2} = \frac{h c}{λ_{32}} λ_{32} = \frac{h c}{E_{3} - E_{2}} λ_{32} = \frac{6.63 \cdot 10^{- 34} \cdot 3 \cdot 10^{8}}{- 13.6 \cdot 8^{2} \cdot 1.6 \cdot 10^{- 19} \cdot (\frac{1}{3^{2}} - \frac{1}{2^{2}})} λ_{32} = 10.26 nm$

In the same approach, we can determine out $4 \to 2$ and $5 \to 2$ transitions:

$λ_{42} = \frac{h c}{E_{4} - E_{2}} λ_{42} = \frac{6.63 \cdot 10^{- 34} \cdot 3 \cdot 10^{8}}{- 13.6 \cdot 8^{2} \cdot 1.6 \cdot 10^{- 19} \cdot (\frac{1}{4^{2}} - \frac{1}{2^{2}})}$

$λ_{42} = 7.6 nm λ_{52} = \frac{h c}{E_{5} - E_{2}} λ_{52} = \frac{6.63 \cdot 10^{- 34} \cdot 3 \cdot 10^{8}}{- 13.6 \cdot 8^{2} \cdot 1.6 \cdot 10^{- 19} \cdot (\frac{1}{5^{2}} - \frac{1}{2^{2}})} λ_{52} = 6.79 nm$

These wavelengths are all in the UV range.
