Helium is the second element on the periodic table of the elements[1]. It is also the second most abundant element in the universe, after hydrogen. Evolutionists belive that helium was created initially in the Big Bang [2]; however this is disputed by creationists. [3] Both groups generally agree is that subsequently helium has been created by by nuclear fusion in the center of stars [4]. Helium is also the by-product of alpha-particle radioactivity. Radioactive decay of heavy elements deep inside the Earth sends Helium leaking into natural gas wells, from which it is obtained for commercial use.
Helium has an interesting history; during the nineteenth century, one of the things some scientists declared to be "impossible"[5] was the determination of the chemical makeup of the stars. Then spectroscopy was developed, and the composition of the stars became known in great detail. Helium, in particular, was discovered in the Sun (as an unknown element) before it was discovered on the Earth. It was, accordingly, named after helios, the Greek for the Sun. It was first found in natural gas in 1905 at the University of Kansas. [6].
