...Argon, krypton, xenon, neon, helium and niton are called ''the noble gases" because, like supercilious bluebloods, they disdain to enter into chemical compounds with other substances. As long ago as 1896 noble argon was thought to have been caught in a fleeting intimacy with water, but that and other reported associations of the noble gases were so dubious that chemistry textbooks continue to label the six gases "inert, incapable of forming compounds...
...patient work by bulky, plural-chinned Harold Simmons Booth and his co-workers at Western Reserve University. Early in their experiments it appeared that in boron trifluoride, the boron "accepted electrons" (i. e., was the go-between) in forming compounds with certain other elements. Why not with aristocratic argon...
Visible Atoms. Academy members had the privilege of beholding, projected on a screen, photographs of three kinds of atoms. The helium atom appeared as a vague blob of electricity. In the neon atom the inner & outer groups of orbital electrons were clearly distinguishable. In the argon atom the inner and middle electron groups showed as one blurred ring, but separate from the outer group. The images were composite photographs of billions of atoms resolved into single pictures by photographing a revolving plate the shape of which was determined by x-ray diffraction. Though indirect, complex and laborious, the method...
...Keith Clark snatches six cigarets, a cigar and finally a pipe from the air, astounds spectators as thoroughly as does Cardini, "The Suave Deceiver" in RKO vaudeville with the same trick. At one point the chorus parades around a dark stage with long glass tubes of rare gases (neon, argon) exposing them to an electro-magnetic field from time to time so that they light up in weird pale colors (''first time on any stage" I. The behavior of The Most Beautiful Girls In The World is a little subdued this year. Presumably as a result of Mayor...
...scientists had already learned that by using other gases they could get other colors-argon & mercury vapor for blue, the same combination in a yellow tube for green, carbon dioxide for white. The gases are confined in the tubes at low pressures (5 to 10 millimetres, compared to 760 millimetres in the sea-level atmosphere). The gases are made to glow by an alternating electric current flowing through them. Because of the penetrating quality of the infra-red rays given off, neon lamps are used as fog beacons, airfield lights...
