Parts of a helium atom

Helium | He - PubChem Helium is a colorless odorless gas. It is lighter than air. It is nonflammable and is only slightly soluble in water. It is chemically inert. When shipped as a liquid it is very cold and will solidify all other gases. Contact with the liquid will cause severe frostbite.
