though hydrogen contains only one electron, why does it show many lines in a spectrum?

Expert Answer:

A hydrogen atom has only one electron, but the emission lines are generated when that electron falls from a high energy state to a lower energy level.

As the single electron of hydrogen can jump to many different energy levels, each energy level produces a photon of different wavelength as it moves from one level to another. This results in multiple emission lines.
