Statement (S): H-atom has only one electron in its orbit, but several spectral lines are noticed

Explanation (E): The

\mathrm{H}

-spectra is observed in

\mathrm{H}_2

gas

View answer and explanation

Correct option: C

Both S and E are correct and E is correct explanation of S

Option A is incorrect. The explanation is wrong, it should be that the H-spectra is observed in a sample of H atoms, not H2 gas. The spectral lines arise from electronic transitions within the H atom.
