With the aim of discovering the missing noble gases in the periodic table, Morris M. Travers and Sir William Ramsay studied liquefied air in 1898. Though the air was already known to contain 99.5% of oxygen, argon and nitrogen, it was difficult to identify the remaining 0.05%. To identify the unknown part, the chemists first extracted a large volume of argon followed by nitrogen and oxygen using magnesium and red-hot copper. The remaining gas was placed in a vacuum tube to which a high voltage was appliSee more on azom kr b chemical propertyKrypton (Kr) - Chemical properties, Health and kr b chemical propertyIt is characterised by its brilliant green and orange spectral lines.
