The noble gases are the members of group 18 of the periodic table: helium, neon, argon, krypton, xenon, radon and, in some cases, oganesson. Under standard conditions, the first six of these elements
Thanks to its characteristic spectral lines, Helium was discovered to exist on the Sun before it was discovered on Earth.
Liquid helium is used to cool superconducting magnets in modern MRI scanners.
