The helium atom exhibit more visible emission lines than hydrogen atom as hydrogen has one electron per atom, while helium atom has two electrons per atom.
Emission lines are generally used to determine the atoms and the molecules.
A emission line is formed when a electron falls behind the low-level state of energy by freeing a photon.
