Helium by I ain't telling you!!! Pierre Janssen discovered helium in the sun in 1868. Janssen originally thought it was sodium, but Joseph Norman Lockyer noticed that it didn't correspond to the D1 and D2 lines of sodium. He named it the "D3" line. Lockyer said that the element D3 was unknown on Earth. He and Edward Franklin concluded on the name Helios after the Greek god of the sun. Helium is found everywhere in space. All natural gases have at least a little bit helium in them. Sir William Ramsey first discovered Helium on Earth by in uranium mineral clevite in the year 1895. When he heated the uranium mineral clevite, he noticed a bright yellow light in its spectrum. It looked the same as the D3 line that was found in the sun. It was concluded that this was the element helium. In 1903, Ramsey also discovered that helium is a product of the spontaneous disintegration of radioactive substances. In 1907 Rutheford and Royds demonstrated that all alpha particles are helium nuclei. The largest compounds of helium are found in the cosmos. About 23 percent of the mass of the universe is helium. This makes it the second most common element behind hydrogen. Helium is mostly concentrated in stars where it combines with hydrogen to create nuclear fusion. Helium is created in stars by nuclear fusion of hydrogen. Helium is found on the Earth as well, but it is not as abundant as it is in space. Only 0.0005 percent of helium occurs in the Earth's Atmosphere, as opposed to 23 percent in space. On Earth, helium is mostly found as a component in natural gases. This means that they helium is a natural gas. Helium is mostly found in the United States, Especially in Texas, New Mexico, Kansas, Oklahoma, Arizona and Utah. Helium has also been found in smaller quantities in Canada, South Africa, and the Sahara Desert. Helium gas is extracted from natural gases by liquefying the gases at low temperatures and high pressures. With most gases, this produces ...
