WebThe helium atom, unlike the hydrogen atom is not magnetic. We could account for the absence of a magnetic moment for helium if we assumed that of the two electrons in the helium 1s orbital, one had its magnetic moment component up () and the other down (¯). The two components would then cancel and there would be no resultant magnetic effect. http://www.chem4kids.com/files/elements/002_shells.html
