Helium: meaning, definitions and examples
๐
helium
[ หhiหliษm ]
chemical element
Helium is a colorless, odorless, tasteless, non-toxic, inert monatomic gas that heads the noble gas group in the periodic table and has the chemical symbol He and atomic number 2. It is the second lightest and second most abundant element in the observable universe, primarily formed during the Big Bang and in stars through nuclear fusion. Helium is used in various applications, including as a lifting gas in balloons, in cryogenics, and as a coolant for superconducting magnets. Due to its low boiling and melting points, helium remains in gaseous form at extremely low temperatures, making it invaluable in scientific research.
Synonyms
light gas, noble gas
Examples of usage
- The balloon was filled with helium.
- Helium is used in deep-sea diving tanks.
- Scientists rely on helium for their experiments.
- The voice of the clown changed after inhaling helium.

Etymology
The name 'helium' is derived from the Greek word 'helios', meaning 'sun'. The gas was first identified in the solar spectrum during a total solar eclipse in 1868 by the French astronomer Pierre Janssen and later confirmed by the English astronomer Joseph Norman Lockyer, who proposed the name helium in reference to its solar origin. The first helium on Earth was discovered in 1895 by the Scottish chemist William Ramsay when he was isolating radium from uranium ore. Helium was once elusive and was thought to originate solely from the sun until it was later found to exist in significant quantities on Earth. Its isolation and commercial production began in the early 20th century, driven by the demand for lighter-than-air balloons and later for various scientific and industrial applications.
