Morris, William

Sir William Ramsay (1852-1916) and Morris William Travers (1872-1961) discovered it spectroscopically in the low-temperature fractionation of crude argon. 

Krypton - the atomic number is 36 and the chemical symbol is Kr. The name derives from the Greek kryptos for concealed or hidden . It was discovered in liquified atmospheric air by the Scottish chemist William Ramsay and the English chemist Morris William Travers in 1898. 

Sir William Ramsay (1852-1916) and Morris William Travers (1872-1961) discovered three new elements in just three months in 1898. They were krypton (May), neon (June), and xenon (July). The most difficult to identify was xenon because Ramsay and Travers needed to produce 10,000 pounds of liquid krypton in their refrigeration equipment in order to obtain just one pound of xenon. This was possible because of xenon s high critical temperature and because xenon s density is greater than oxygen s.

Krypton was one of three noble gases discovered in 1898 by Scottish chemist and physicist Sir William Ramsay (1852—1916) and English chemist Morris William Travers (1872—1961). Ramsay and Travers discovered the gases by allowing liquid air to evaporate. As it did so, each of the gases that make up normal air boiled off, one at a time. Three of those gases— krypton, xenon, and neon, were discovered for the first time this way. 

Curie discover the elements radium and polonium. Marie Curie coins the term radioactivity after her study of these elements. Scottish chemist William Ramsay and English chemist Morris William Travers discover the elements krypton, neon, and xenon. Scottish chemist Sir James Dewar produces liquid hydrogen. 

The two noble gases known from 1895 had the atomic weights 4 (He) and 40 (Ar). Ramsay concluded that there should exist a gas in between, with an atomic weight about 20. He now cooperated with Morris William Travers (1872-1961), 20 years younger than himself, and an authority on glass technology. The two scientists started a project in order to find that element.
