Strutt was born on 12 November 1842 at Langford Grove, Maypole Road in Maldon, Essex. [3] In his early years he suffered from frailty and poor health. [ 4 ] He attended Eton College and Harrow School (each for only a short period), [ 5 ] before going on to the University of Cambridge in 1861 where he studied mathematics at Trinity College .
Argon is a chemical element; it has symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. [10] Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv).
Chemical elements are sometimes named after people, especially the synthetic elements discovered (created) after c. 1940. Very few are named after their discoverers, and only two have been named after living people: the element seaborgium was named after Glenn Seaborg , who was alive at the time of naming in 1997; [ 5 ] and in 2016 oganesson ...
Sir William Ramsay KCB FRS FRSE (/ ˈ r æ m z i /; 2 October 1852 – 23 July 1916) was a Scottish chemist who discovered the noble gases and received the Nobel Prize in Chemistry in 1904 "in recognition of his services in the discovery of the inert gaseous elements in air" along with his collaborator, John William Strutt, 3rd Baron Rayleigh, who received the Nobel Prize in Physics that same ...
Perey discovered it as a decay product of 227 Ac. [177] Francium was the last element to be discovered in nature, rather than synthesized in the lab, although four of the "synthetic" elements that were discovered later (plutonium, neptunium, astatine, and promethium) were eventually found in trace amounts in nature as well. [178]
For instance, argon, krypton, and xenon form clathrates with hydroquinone, but helium and neon do not because they are too small or insufficiently polarizable to be retained. [61] Neon, argon, krypton, and xenon also form clathrate hydrates, where the noble gas is trapped in ice. [62] An endohedral fullerene compound containing a noble gas atom
