Helium is itself a chemical element and therefore is not found in any other chemical element.
Helium is found as a mono atomic element. It is not found as a mineral.
The element 'helium' is named after 'Helios' (the sun) as the element was first found in the sun. 25 years later is was then found on earth.
The elemental symbol for helium is ' He ' , and is found in the Periodic Table in position ( Atomic No.) two(2).

Helium has 2 valence electrons.
Helium (He) is an element. Helium is the most inert element of all, and does NOT form compounds. It is found in the Periodic Table as Atomic No. 2. It has an atomic mass of '4' Its symbol is [4/2]He The name ' helium' comes Classical Greece, and means 'of the Sun(helios)'. Because two atoms of hydrogen in the Sun fuse together form 'helium'.
I think it is hydrogen
Helium is not found in caffeine. Caffeine is made up of carbon, hydrogen, nitrogen, and oxygen atoms. Helium is a noble gas and is typically not found in organic compounds like caffeine.
It is a element
Helium is a natural element that is extracted from underground gas deposits through a process called helium mining. It is not synthetic, but rather a naturally occurring element found in the Earth's crust.
