percent of abundance of helium on earth
Helium is the second lightest element in the known universe. It is also the second most abundant. According to some estimates helium accounts for as much as 24 percent of the Universeâs mass. This element is also plentiful since it is a prime product of fusion nuclear reactions involving hydrogen. So if it is so plentiful where is Helium found?
Helium is pronounced as HEE-lee-em. History and Uses: Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth. Pierre-Jules-Cesar CÃ©sar, janssen A french, astronomer noticed a yellow line in the'sun s spectrum while studying a total solar eclipse in. 1868wo Swedish chemists, Nils Langlet and Per Theodor Cleve, independently found helium in clevite at about the same time as Ramsay.
