The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). Oganesson (Og) is a synthetically produced highly radioactive ...
Argon is used because of its inert properties for protection against the oxidizing effect of air. Argon is widely used as a blanketing or shielding gas in metallurgy ...
Like all noble gases, xenon is colourless ... remained undiscovered until Lord Rayleigh and William Ramsey isolated argon in 1894. Remarkably, Ramsey then went on to isolate helium (1895) and ...
(The helium-neon laser emits on neutral neon lines.) A pulsed xenon ion laser, with somewhat different characteristics than other noble gas ion lasers, is described briefly in Chap. 16. The prime ...
