He(Helium)

Helium (He) is a colorless, odorless and tasteless inert monoatomic gas. Liquid helium is used at low temperatures, especially in the cooling of superconducting magnets, such as in MRI scanners. In industry, helium has many uses, for example as pressurization and purge gas, shielding gas during arc welding, and chemical reaction process involved in crystal manufacturing.
