Question

The energy emitted when electron of 1.0 g atom of hydrogen undergoes transition giving the spectral lines of lowest energy in the visible region of its atomic spectra is

Options

A.301.22 kJ
B.328 kJ
C.984 kJ
D.182.22 kJ

Solution

$\Delta E = 1312 \times \left( \frac{1}{2^{2}} - \frac{1}{3^{2}} \right) = 182.22\text{ KJ}$
