Etymology
He is the chemical symbol for helium, a name that comes from Greek Helios, meaning 'sun', because scientists first found the gas in the light of the sun. The symbol He keeps that name, so when you see He on a balloon or in a lab it means the very light gas helium that makes balloons float and helps cool scientific equipment.
