Today we learn at such a young age about the periodic properties of the elements and their atomic structure that it seems as if we grew up with the knowledge, and that everyone must always have known such basic, simple stuff. But till nearly the end of the nineteenth century no one even suspected that such things as the noble gases, with their filled ...

Abstract Helium is one of the rare gases. It was discovered on the sun, and first was found on earth in quantity in natural gases from Kansas. It has unique properties which make it increasingly valuable to industry and science. Most helium on earth is believed to have originated from the decay of radioactive minerals.
