Web23 mrt. 2024 · Helium gets ionized in a vacuum where its ions are subsequently accelerated and separated in a magnetic field. The current generated from the ions is converted to electric current and that is what is displayed as the detection value. This is because the current generated is directly proportional to the concentration of helium. WebThe hydrogen spectrum is an important piece of evidence to show the quantized electronic structure of an atom. The hydrogen atoms of the molecule dissociate as soon as an electric discharge is passed through a gaseous hydrogen molecule. It results in the emission of electromagnetic radiation initiated by the energetically excited hydrogen atoms.
