Research On Other Areas of Inorganic Chemistry

In 1921, he first prepared metallic beryllium by electrolyzing a fused mixture of sodium and beryllium fluorides. This method made beryllium available for industrial use, as in special alloys and glasses and for making windows in X-ray tubes.

He was also influential in coordination chemistry. The term "ligand" (from ligare Latin, to bind) was first used by Stock in 1916. H. Irving and R.J.P. Williams adopted the term in a paper published in 1948. Monodentate, bidentate, tridentate characterized the number of ligands attached to a metal. Given the introduction of ligand concept, he was also able to further derive the idea of bite angle and other aspects of chelation.

The "Stock system," first published in 1919, was a means of nomenclature on binary compounds. In his own words, he considered the system to be "simple, clear, immediately intelligible, capable of the most general application." In 1924, a German commission recommended Stock system to be adopted with some accommodations. FeCl2, which would have been named iron(2)-chloride according to Stock's original idea, became iron(II) chloride in the revised proposal. In 1934 Stock agreed to the use of Roman numerals but preferred keeping the hyphen and dropping the parentheses. Although this suggestion has not been followed, the Stock system remains in use worldwide.

Famous quotes containing the words research, areas, inorganic and/or chemistry:

    The great question that has never been answered and which I have not get been able to answer, despite my thirty years of research into the feminine soul, is “What does a women want?”
    Sigmund Freud (1856–1939)

    If a walker is indeed an individualist there is nowhere he can’t go at dawn and not many places he can’t go at noon. But just as it demeans life to live alongside a great river you can no longer swim in or drink from, to be crowded into safer areas and hours takes much of the gloss off walking—one sport you shouldn’t have to reserve a time and a court for.
    Edward Hoagland (b. 1932)

    Man, unlike anything organic or inorganic in the universe, grows beyond his work, walks up the stairs of his concepts, emerges ahead of his accomplishments.
    John Steinbeck (1902–1968)

    Science with its retorts would have put me to sleep; it was the opportunity to be ignorant that I improved. It suggested to me that there was something to be seen if one had eyes. It made a believer of me more than before. I believed that the woods were not tenantless, but choke-full of honest spirits as good as myself any day,—not an empty chamber, in which chemistry was left to work alone, but an inhabited house,—and for a few moments I enjoyed fellowship with them.
    Henry David Thoreau (1817–1862)
