. A sample of ordinary hydrogen (H) gas in a discharge tube was seen to emit the usual Balmer spectrum. On careful examination, however, it was found that the H line in the spectrum was split into two fine lines, one an intense line at 656.28 nm, and the other a faint line at 656.04 nm. From this one can conclude that the gas sample had a small impurity of?

Explanation:

The splitting of the H line in the Balmer spectrum of hydrogen gas indicates the presence of a small impurity. This phenomenon is known as fine structure splitting and is caused by the interaction of the electron's spin with its orbital angular momentum. The presence of two fine lines at slightly different wavelengths suggests that the impurity is a different isotope of hydrogen, known as deuterium.

Fine structure splitting:
Fine structure splitting occurs due to the interaction of the electron's spin and its orbital angular momentum. The electron in a hydrogen atom can occupy different energy levels, and the Balmer series corresponds to transitions between the second energy level (n=2) and higher energy levels. However, within the n=2 energy level, there are sublevels with different values of orbital angular momentum (L) and spin angular momentum (S). The interaction between these two angular momenta leads to the splitting of spectral lines into multiple components.

Deuterium:
Deuterium is an isotope of hydrogen that contains a neutron in addition to the proton in its nucleus. Unlike ordinary hydrogen, which has only a single proton, deuterium has both a proton and a neutron. This difference in mass leads to a slight difference in the energy levels of the electron in deuterium compared to ordinary hydrogen.

Line splitting:
The intense line at 656.28 nm corresponds to the transition between the n=2 energy level and a higher energy level in ordinary hydrogen. However, the faint line at 656.04 nm suggests the presence of an impurity with a slightly different energy level. This impurity is likely deuterium, as it has a different mass and therefore different energy levels compared to ordinary hydrogen.

Conclusion:
Based on the observation of the splitting of the H line in the Balmer spectrum of hydrogen gas, with two fine lines at slightly different wavelengths, it can be concluded that the gas sample had a small impurity of deuterium. Deuterium is an isotope of hydrogen with a slightly different mass, which leads to a difference in energy levels and the splitting of spectral lines.
