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).
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 .
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 ...
Morris William Travers, FRS (24 January 1872 – 25 August 1961) was an English chemist who worked with Sir William Ramsay in the discovery of xenon, neon and krypton. [1] His work on several of the rare gases earned him the name Rare Gas Travers in scientific circles. [2]
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]
The abundance of argon, on the other hand, is increased as a result of the beta decay of potassium-40, also found in the Earth's crust, to form argon-40, which is the most abundant isotope of argon on Earth despite being relatively rare in the Solar System. This process is the basis for the potassium-argon dating method. [72]
Hughes, one of our truest American compasses, entered the world on the first day of February 1901, born in Joplin. His family would purposefully roam, and Hughes spent much of his youth in Kansas ...
