Background

Helium is a rare gas, is a colorless and odorless inert gas with the element symbol He and the atomic number, is chemically inert, and is generally difficult to react with other substances. Helium is an extremely light, colorless, odorless, and tasteless monatomic gas at ambient temperature. Is the most difficult of all gases to liquefy and is a substance that cannot solidify at standard atmospheric pressure. When the temperature is reduced to 2.174K after liquefaction, the material has the special properties of small surface tension, strong heat conductivity, extremely low viscosity and the like. Low temperatures close to absolute zero can be achieved with liquid helium. Stable chemical performance and deep yellow color when low-voltage discharge is carried out. Generally, no compounds are formed, and He2+, HeH plasma and molecules are formed when excited in a low-pressure discharge tube.
