Say what? Helium is pronounced as HEE-lee-em. Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth. Pierre-Jules-CÃ©sar Janssen, a French astronomer, noticed a yellow line in the sun's spectrum while studying a total solar eclipse in 1868.
Helium is an inert gas and does not easily combine with other elements. There are no known compounds that contain helium, although attempts are being made to produce helium diflouride (HeF 2). Estimated Crustal Abundance: 8Ã10 -3 milligrams per kilogram. Estimated Oceanic Abundance: 7Ã10 -6 milligrams per liter.
