Question

Hydrogen has only 1 electron but why there are so many lines in the spectrum?EXPLAIN

Answer 1

Hydrogen has only 1 electron but there are so many lines in the spectrum. When we started the experiment of the line spectrum with Hydrogen then the number of hydrogen molecule is infinite. when every H2 molecule jumps from excited state to ground state then the H2 molecule gives magnetic rays. Many molecules are gives this rays then hydrogen has only 1 electron but we have so many lines in the spectrum.

Answer 2

Although  hydrogen atom has only one electron,which orbiting its nucleus.The electromagnetic force between electron and nuclear photons leads a set of quantum state because  it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted,each with its own energy ,and the energy difference of the shells causes different wavelengths to be released... hence, mono-electronic hydrogen has many spectral lines.
