The isolation and identification of 4 radioactive elements in minute amounts took place at the turn of the century, and in each case the insight provided by the periodic classification into the predicted chemical properties of these elements proved invaluable. Marie Curie identified polonium in 1898 and, later in the same year working with Pierre Curie, isolated radium. Actinium followed in 1899 (A. Debierne) and the heaviest noble gas, radon, in 1900 (F. E. Dorn). Details will be found in later chapters which also recount the discoveries made in the present century of protactinium (O. Hahn and Lise Meitner, 1917), hafnium (D. Coster and G. von Hevesey, 1923), rhenium (W. Noddack, Ida Tacke and O. Berg, 1925), technetium (C. Perrier and E. Segre, 1937), francium (Marguerite Percy, 1939) and promethium (J. A. Marinsky, L. E. Glendenin and C. D. Coryell, 1945).

Jacob A. Marinsky ( 1918) as well as L. E. Glendenin and Charles D. Coryll ( 1912) detected the element at Oak Ridge. The first conclusive proof was in uranium piles. Uranium fission gives rise to fragments with nuclei of atomic number 61. 

Promethium (Pm, [Xe]4/56s2), name and symbol after Prometheus who, in Greek mythology, stole fire from the gods. Discovered (1945) by J.A. Marinsky, L. Glendenin and C.D. Coryell by use of ion-exchange chromatography on residues in a nuclear reactor.

The discovery of this element is credited to J.A. Marinsky and L.E. Glendenin who, in 1945, identified its long-lived isotope Pm-147 (ti/2 2.64 years) in the fission products of uranium. They named the element after Prometheus, who according to Greek mythology stole fire from heaven. The element was first isolated from fission product wastes by G.W. Parker and P.M. Lantz in 1948. It first was recovered from natural sources by O. Erametsa in 1965. An amount less than 0.5 g was recovered from 20 tons of rare earths. 

Aft er many false reports of its occurrence in nature, promethium was finally identified in 1947 in fission productsby Jacob A. Marinsky, Lawrence E. Glendenin, and Charles D. Coryell. It was named after the Greek mythological character Prometheus who stole fire from the heavens. No stable isotopes of Pm exist, its longest lived isotope being Pm-145 (half life 17.7 years), but... 

Charles D. Coryell, 1912-. Professoi of chemistry at the Massachusetts Institute of Technology. Consultant to the Brookhaven and Oak Ridge National Laboratories of the United States Atomic Energy Commission. The studies of J. A. Marinsky and L. E. Glendenin in his group led to the chemical identification of the missing element 61, which in 1949 was officially named promethium. Dr. Coryell participates actively in the scientific efforts of the Federation of American Scientists and of the United World Federalists toward peace and world stability. 

The final answer came from the atomic pile. J. A. Marinsky, L. E. Glendenin, and C. D. Coryell at the Clinton Laboratories at Oak Ridge (20) obtained a mixture of fission products of uranium which contained isotopes of yttrium and the entire group of rare earths from lanthanum through europium. Using a method of ion-exchange on Amberlite resin worked out by E. R. Tompkins, J. X. Khym, and W. E. Cohn (21) they were able to obtain a mixture of praseodymium, neodymium, and element 61, and to separate the latter by fractional elution from the Amberlite column with 5 per cent ammonium citrate at pH 2.75. Neutron irradiation of neodymium also produced 61.
