28 wrz 2024 · Sir William Ramsay was a British physical chemist who discovered four gases (neon, argon, krypton, xenon) and showed that they (with helium and radon) formed an entire family of new elements, the noble gases. He was awarded the 1904 Nobel Prize for Chemistry in recognition of this achievement.
Xenon was discovered in England by the Scottish chemist William Ramsay and English chemist Morris Travers on July 12, 1898, [29] shortly after their discovery of the elements krypton and neon. They found xenon in the residue left over from evaporating components of liquid air.
Xenon was discovered in July 1898 by William Ramsay and Morris Travers at University College London. They had already extracted neon, argon, and krypton from liquid air, and wondered if it contained other gases.
The story of xenon begins in 1894 when Lord Rayleigh and William Ramsay were investigating why nitrogen extracted from chemical compounds is about one-half per cent lighter than nitrogen extracted from the air - an observation first made by Henry Cavendish 100 years earlier.
8 paź 2024 · The British chemists Sir William Ramsay and Morris W. Travers isolated the element in 1898 by repeated fractional distillation of the noble gas krypton, which they had discovered six weeks previously.
31 gru 2008 · Xenon was discovered on 12 July 1898 by William Ramsay and Morris William Travers at University College London. They had already isolated neon, argon and krypton by fractional distillation of liquid air and, using the same method, eventually isolated a heavier gas, which they called xenon from the Greek word xenos, meaning strange.
Xenon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, on July 12, 1898, shortly after their discovery of the elements krypton and neon. Like krypton and neon, xenon was discovered through the study of liquefied air.
