Web27 aug. 2024 · The reason we will not run out is that hydrogen forms bonds with other atoms besides itself. The element is bound into water molecules and organic compounds. Helium, on the other hand, is a noble gas with a stable electron shell structure. Since it doesn't form chemical bonds, it isn't preserved in compounds. Cite this Article.
