Respuesta :

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.

What are emission lines?

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.

Difference between the helium visible emission lines and hydrogen visible emission lines-

  • Main difference between the helium visible emission lines and hydrogen visible emission lines, that the helium visible emission exhibit more lines.
  • These emission lines are the formations of wavelength of electromagnetic radiation, emitted by the helium and hydrogen atom.
  • This is because hydrogen has one electron per atom, while helium atom has two electrons per atom.

Hence, 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.
