Therefore, the chemical properties of rare gases are very inactive, so people used to think that they would not react chemically with other elements and were called "inert gases". However, it is this absolute concept that binds people's thinking and hinders the study of rare gas compounds. 1962, N.Bartlett, a 26-year-old young British chemist working in Canada, synthesized the first rare gas compound Xe[PtF6], which aroused great interest and concern in the chemical field. Many chemists competed to carry out this work, and successively synthesized a variety of "rare gas compounds", which promoted the development of rare gas chemistry. The name "inert gas" is no longer true, so it was renamed as rare gas.
