Web28 de jun. de 2016 · Helium is all over the universe—it’s the second-most abundant element. But on Earth, it’s much less common. It can’t be artificially produced and must be extracted from natural gas wells. In the Earth's heterosphere, a part of the upper atmosphere, helium and other lighter gases are the most abundant elements. Most helium on Earth is a result of radioactive decay. Helium is found in large amounts in minerals of uranium and thorium, including uraninite and its varieties cleveite and … Ver mais Helium (from Greek: ἥλιος, romanized: helios, lit.
