Travers, 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. 

Although a noble gas, krypton is not entirely unreactive. One krypton compmmd, krypton difluoride (KrF2), is commercially available in small quantities. SEE ALSO Gases Noble Gases Ramsay, William Travers, Morris. 

Neon is produced within stars during nucleosynthesis. It has three stable isotopes, of which neon-20 is the most abundant (90.5%). see also Gases Noble Gases Ramsay, William Travers, Morris. 

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.

The lightest noble gas, helium, had in fact been discovered in 1868 -but only on the sun (see pages 73-4). So little was known about it that Mendeleyev could see no way to include it. Helium was not found on Earth until 1895, when William Ramsay and Morris Travers in London isolated it from uranium minerals. Two Swedish chemists in Uppsala found it in much the same source at the same time. 

In Morris Travers account of Ramsay s life and work, it was mentioned twice that Ramsay suggested Williams repeat the Cavendish experiment on air. It was the later repetition of Cavendish s experiment by others that resulted in the discovery of the noble gases ... 

Neon was discovered in 1898 by British chemists William Ramsay (1852—1916) and Morris Travers (1872—1961). It occurs naturally in the atmosphere, but only in very small amounts. 

English chemists Sir William Ramsay and Morris Travers discover krypton, neon, and xenon. 

The name comes from the Greek xenon, meaning stranger. Xenon was discovered by William Ramsay (1852-1916) and Morris W. Travers (1872-1961) in 1898 as part of their search for a noble gas between helium and argon. It is present as a trace element in atmospheric air. It is the heaviest of the noble gases. It is used commercially in specialty lamps and lasers, as well as in sophisticated laboratory equipment such as bubble chambers and as a radioactive isotope used as a tracer. 

Krypton (from the Greek word kryptos, meaning hidden ), is the second heaviest of the nohle gases. It was discovered in 1898 by Sir William Ramsay and Morris Travers dining their experiments with bquid air, air that has been bquefied by coobng. It has a concentration of 1.14 ppm by volume in Earth s atmosphere. It is present in the Sun and in the atmosphere of Mars. 

Xenon (its name derived from the Greek word xenos, meaning strange ), is the heaviest of the noble gases. Discovered in 1898 in London by Sir William Ramsay and Morris Travers while engaged in their investigations of liquid air, xenon accounts for less than 1 ppm of the volume of Earth s atmosphere. It is present in the Snn and in the atmospheres of Mars, Venus, and Mercury.
