a hydrogen gas - filled discharge tube was activated. with one electron and one proton, hydrogen is the simplest element and gives the simplest line spectrum. there are only four lines in the visible region of the hydrogen spectrum, at 656 nm (red), 486 nm (blue - green), 434 nm (blue - violet), and 411 nm (violet). however, it was observed that there was a fifth line in the spectrum of hydrogen. what could be the reason for this? a the hydrogen gas used was ionized. b the gas used had traces of another element. c the diffraction gradient distorted the spectrum d the disintegration of the emitted photons of energy.

Answer

Brief Explanations:

Each element has a unique line spectrum. If there is an extra line in the hydrogen spectrum, it is likely due to the presence of another element. Ionized hydrogen ((H^+)) has no electron to emit light for a line - like spectrum in this context. A diffraction gradient causing a distortion would not create a new distinct line (as in a new wavelength corresponding to a new element's spectral line). The disintegration of emitted photons is not a valid scientific reason for an extra line in the spectrum.

Answer:

B. The gas used had traces of another element.
