Did you know?
- Helium was discovered in 1868 by Jules Janssen.
- Its name comes from the Greek "ἥλιος" (helios) meaning "sun".
- Helium is abundant in the sun's atmosphere and is found at trace levels in Earth's atmosphere. However, it may also be found in fossil form in natural gas pockets in some oil fields, extracted by drilling deep into the subsoil.
- Helium is an extremely light gas and is therefore very volatile.
- It is colorless, odorless, non-flammable and completely inert.
