With an air of "There, that will convince them," Professor Fred Allison of Alabama Polytechnic Institute last week slapped on his desk a fresh copy of the American Chemical Society's Journal. "Them," referred to everyone who doubted that Professor Allison had discovered Element No. 87, or eka-cesium. in 1930 and Element No. 85, or eka-iodine last April by means of his new magneto-optical machine...
...Them" referred particularly to Professor Jacob Papish of Cornell, who last autumn recognized eka-cesium with the x-ray spectrograph. With an x-ray spectrograph Professor B. Smith Hopkins of the University of Illinois discovered the third last unknown element, No. 61, of the Periodic Table, which he named illinium (TIME, March...
...every element and every form of every element, it is a delicate analyzer of unknown substances. It can discern one trillionth of a part of a foreign substance in anything presented to its wrenching beam. Last week's triumph of Professor Allison was his ability to state that eka-cesium had six very similar forms or isotopes. No. 87 belongs to the base-forming family of elements which include lithium, sodium, potassium, rubidium, cesium. Professor Allison, 50, asked scientists to call the element virginium. after the State of his birth. He asked them to call Element...
Element No. 87's discovery was claimed last year by Dr. Fred Allison of Alabama Polytechnic Institute. Recently he said he had found No. 85, ekaiodine, the other unisolated element. Professor Jacob Papish also claimed discovery of No. 87, eka-cesium. He told the Academy he had made tests with Dr. Allison's magneto-optic device, found chemical mixtures sometimes made it register elements not really present...
...method was to take materials which he reasoned might contain eka-iodine. Since eka-iodine would be a halide like fluorine, chlorine, bromine and iodine, only heavier, he used seawater, fluorite and other halogen compounds. He burned each of them and sent their complex light through a polariscope and then through a magnetic field. A magnet twists polarized light to a calculable extent. The fineness of this magneto-optic rotation is such that it can detect one part of a substance in 100 billion parts. The greatest amount of eka-iodine Dr. Allison could find in any of his substances...
