Another profound fact Professor Compton discovered. Atoms are made up of a nucleus with a positive charge of electricity and one or more electrons with negative charges. The electrons (they are all the same size no matter what the element) revolve around their nucleus in a symmetrical pattern. Hydrogen, lightest of elements, has only one electron whirling around its nuclear "sun." Heavy metals, like lead, radium and uranium, have many electrons. In some elements some of the electrons pop away from their atoms. Such elements are radioactive. X-rays can make them pop away violently. When x-rays...
...organic chemistry. Before him chemists thought that they could make compounds only of inorganic elements, that organic growths depended upon a "vital principle." Berthelot reasoned that all chemical phenomena followed physical laws. In his laboratory he treated glycerin with certain acids and got fats, oils and butters. He combined hydrogen and carbon by means of the voltaic arc and got acetylene. "Berthelot condenses it [acetylene] under the action of heat and behold, we have benzine," writes Premier Poincaré in the current Chimie et Industrie, French periodical. "He adds hydrogen and behold, there appears ethylene, which, united with water, will...
Small Balloon. One Leo Stevens rode 350 miles in a 50-pound balloon. Standing in the vaselike basket, too narrow to sit down, he traveled all night from Englewood, N. J. to the vicinity of Saranac Lake, N. Y. Releasing the hydrogen, he put the bag and basket on his back, and walked to the nearest railroad station...
...granted and, from them, much of the structure of theoretical chemistry has been built up. But water is actually most mysterious, should be studied, said Dean James Kennell of New York University. He reminded his audience that in a world where the active constituent of the atmosphere was hydrogen instead of oxygen, fires would be extinguished, not by throwing on water, but by some hydrocarbon such as gasoline...
...Reduction-powerful pumps compress oxygen, hydrogen or acetylene into tall, slim, thick-walled steel tanks for welding or burning through metal; incandescent bulb makers buy nitrogen and argon-profits...
