Atomic theory

  • Antoine Lavoisier

    Antoine Lavoisier
    Lavoisier found that mass is conserved in a chemical reaction. His results led to one of the fundamental laws of chemical behavior: the law of conservation of matter, which states that matter is conserved in a chemical reaction.
  • Joseph Louis Proust

    Joseph Louis Proust
    He was best known for his discovery of the law of constant composition in 1799, stating that chemical compounds always combine in constant proportions.
  • John Dalton

    John Dalton
    He is best known for his pioneering work in the development of modern atomic theory; and his research into colour blindness, sometimes referred to as Daltonism
  • Micheal Faraday

    Micheal Faraday
    English scientist who contributed to the fields of electromagnetism and electrochemistry. His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis.
  • Henri becquerel

    Henri becquerel
    Further studies made it clear that this radiation was something new - not the same type as X-rays. He had discovered a new phenomenon - radioactivity.
  • JJ Thompson

    JJ Thompson
    Discovered the electron in a series of experiments designed to study the nature of electric discharge in a high-vacuum cathode-ray tube, an area being investigated by numerous scientists at the time.
  • Max Planck

    Max Planck
    a German theoretical physicist who originated quantum theory, which won him the Nobel Prize in Physics in 1918.
  • Marie Curie

    Marie Curie
    Her achievements included a theory of radioactivity , techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium.
  • Robert A. Millikan

    Robert A. Millikan
    Millikan worked on an oil-drop experiment in which he measured the charge on a single electron.
  • Ernest Rutherford

    Ernest Rutherford
    He discovered alpha and beta rays, set forth the laws of radioactive decay, and identified alpha particles as helium nuclei.
  • Lise Meithner

    Lise Meithner
    an Austrian physicist who worked on radioactivity and nuclear physics. Meitner was part of the Hahn-Meitner-Strassmann team that worked on "transuranium-elements"
  • Otto Hahn

    Otto Hahn
    Otto Hahn, OBE, ForMemRS was a German chemist and pioneer in the fields of radioactivity and radiochemistry who won the Nobel Prize in Chemistry in 1944 for the discovery and the radiochemical proof of nuclear fission
  • Albert einstein

    Albert einstein
    The existence of atoms and molecules was confirmed. With Einstein’s calculations, one could determine the size of these invisible atoms and molecules
  • Erwin Schrodinger

    Erwin Schrodinger
    A Nobel Prize-winning Austrian physicist who developed a number of fundamental results in the field of quantum theory, which formed the basis of wave mechanics: he formulated the wave equation.
  • Niels Bohr

    Niels Bohr
    discovery of the nucleus and development of an atomic model had earned him a Nobel Prize in chemistry in 1908
  • James chadwick

    James chadwick
    an English physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932
  • Louis de broglie

    Louis de broglie
    known for his research on quantum theory and for his discovery of wave nature of electrons. He was awarded the 1929 Nobel Prize for Physics
  • Glenn Seaborg

    Glenn Seaborg
    Glenn Theodore Seaborg was an American chemist whose involvement in the synthesis, discovery and investigation of ten transuranium elements earned him a share of the 1951 Nobel Prize in Chemistry.
