Helium
Helium, an inactive element, is a kind of rare gas with the element symbol He. Helium is usually a colorless and tasteless gas, which is the only material that cannot be solidified under standard atmospheric pressure. Helium is mainly used as protective gas, working fluid of gas cooled nuclear reactor and cryogenic refrigerant. In addition, helium can also be used as a buoyant gas because its density is smaller than that of air and its properties are stable.
