WebIt holds the lowest boiling and melting points amongst all other elements. Nuclear fusion of hydrogen in stars generates a significant amount of helium. Isotopes Helium has two known stable isotopes – 3 He and 4 He. The abundance of helium-3 and helium-4 corresponds to 0.0002% and 99.9998% respectively. WebWhat are the Common Uses of Hydrogen. It is used in the production of ammonia, methyl alcohol, and cyclohexane for making agricultural fertilizers, antifreeze agents, chemical solvents, plastics, pharmaceuticals, and precursor chemicals [1, 2]. The element is used in several oil-refining processes to remove sulfur impurities from fuel [1].
