First Known Use: 1872 Etymology: Helium comes from the Greek word for sun, helios. That connection to the sun is the reason why, for nearly three decades after it was first observed, chemists dismissed the element that we use today for everything from filling party balloons to cooling the Large Hadron Collider—and now helium is rapidly diminishing. Helium has a higher diffusion coefficient for carbon dioxide relative to oxygen thus promotes exhalation of trapped carbon dioxide. This reduces hypercapnia and normalizes pH.

Helium is in the family VIII A. This family is also called the Noble Gases. or inert gases. Elements in this family have filled outer electron shells. Because their valance electrons are all paired there is little bonding of these electrons. though some of the larger noble gases do form some bonds.
