      • George Johnston Stoney - Of the Electron, or Atom of Electricity

    George Johnstone Stoney (born Feb. 15, , Oakley Park, King’s County, Ire.—died July 5, , London, Eng.) was a physicist who introduced the term electron for the fundamental unit of electricity.

    HISTORY OF PHYSICS Stoney's - Europhysics News

      He estimated the number of molecules in a cubic millimetre of gas, at room temperature and pressure, from data obtained from the kinetic theory of gases. Stoney's most important scientific work was the conception and calculation of the magnitude of the "atom of electricity".

    Patrick Dublin Institute for Advanced Studies George Johnstone Stoney, the man who named the electron, was led to the concept of a fundamental unit of electric charge by combining electro-chemistry with the kinetic theory of gases.

  • Chemistry Chapter 3-- Atomic Theory Test - Quizlet You could say that the electron, one of nature’s fundamental particles, was invented by the Irish physicist George Johnstone Stoney (). Stoney, born at Oakley Park, Clareen, was the first science professor at the then new university of Queen’s College Galway (now NUI Galway).
  • The man who ‘invented’ the electron | Ingenious Ireland Stoney proposed the particle or atom of electricity to be one of three fundamental units on which a whole system of physical units could be established. The other two proposed were the constant universal gravitation and the maximum velocity of light and other electromagnetic radiations.
  • 2.1: Historical Development of Atomic Theory - Chemistry ... Stoney’s estimate of the fundamental unit of charge was calculated using the amount of hydrogen gas released when water was ‘electrolysed’ by passing an electric current through it. Stoney’s work on the kinetic theory of gases had previously led him to estimate of the number of gas molecules contained in a cubic millimetre [2].


    • George Johnstone Stoney - Wikipedia

    One hundred years ago he determined the charge of the atom or particle of electricity, and he later proposed the name 'electron' for this quantity. This, and related work on the kinetic theory of gases and spectroscopy, was his most conspicuous achievement. Stoney's first important writings were on the molecular-kinetic theory of gases.


      Stoney is best known as the originator of the name, 'electron', for the fundamental unit of electric charge.
    The term “electron” was coined in by Irish physicist George Stoney, “The Development of the Theory of Atomic Structure,” ed. J. A. Ratcliffe, in.
      While experimenting on what he later called electrons, he found that whatever it is that flows in an electric wire, it not a continuous flow.
    Thomson futhered our Atomic knowledge by discovering isotopes,and confirming that atoms did indeed contain particles known as electrons. He discovered this by carrying out experiments with a CRT (Cathort Ray Tube) and proposed that the charge to mass ratio of an electron is x coulombs/gram.
      One hundred years ago he determined the charge of the atom or particle of electricity, and he later proposed the name 'electron' for this quantity.
    Thomson called these particles corpuscles, but they have come to be called electrons, a name suggested by George Johnstone Stoney in Thomson was able to calculate the mass to charge ratio, and the results of his experiments and calculations suggested that electrons were about 1/ the mass of hydrogen atoms, suggesting that atoms are.

    Gentlemen, [p] PROFESSOR EBERT, in his paper on the Heat of Dissociation in last month’s (September) Phil. Mag., says on p. — “Von Helmholtz, on the basis of Faraday’s Law of Electrolysis, was the first to show in the case of electrolytes that each valency must be considered charged with a minimum quantity of electricity, the ‘valency-charge,’ which like an electrical atom.

    History of Atomic Theory -

    The term “electron” was coined in by Irish physicist George Stoney, from “electric ion.” In , more information about the electron was uncovered by American physicist Robert A. Millikan via his “oil drop” experiments.
