Atomic Theory Timeline

  • Antoine Lavoisier

    Antoine Lavoisier
    This man gave the elements carbon, hydrogen, and oxygen their names, discovered oxygens part of combustion and respiration.
  • Micheal Faraday

    This man was the first to produce an electrical current from a magnetic field. He invented the first electric motor and dynamo.
  • Joseph Louis Proust

    Joseph Louis Proust
    This man discovered the law of constant compostiton which is when a chemical compound will always combine in constant proportions. (wiki)
  • John Dalton

    This man identified the hereditary nature of the red-green color blindness., as well as came up with daltons law of partial pressures. First to explain behaviors of atoms by weight. (biograghy.com)
  • Henri Becquerel

    This man played a big role in the discovery of radioactivity.
  • JJ Thompson

    This man discovered the electron by using a high-vaccume cathode-ray tube; an area being looked into by many scientists at this time period.
  • Max Planck

    This scientist is known for his role in originating the quantum theory. The Quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level.
  • Robert Milikan

    He meausred the change of an atom under circumstances and wokred on the photoeletric effect. The photoelectric effect is the observation that many metals emit electrons when light shines upon them.
  • Ernest Rutherford

    He was the first to split in atom. Awarded the nobel prize for his thoery of atomic strucure.
  • Marie Curie

    Marie Curie
    She was the first women to win the Nobel Prize for her discovery of polonium, radium, and the continued development of X-rays.
  • Albert Einstein

    Albert Einstein
    Albert explained the photoelectric effect, and devlopement of atomic energy. Also created the equation e=mc2
  • Niels Bohr

    Niels Bohr
    He came up with a theory on atomic structures and radition emission.
  • Lisa Meitner

    Lisa Meitner
    Lisa played a role in the discovery of radiationless transition known as the auger effect.
  • Louis Debroglie

    Louis Debroglie
    He was a French physicist who made groundbreaking contributions to quantum theory. In his 1924 PhD thesis he postulated the wave nature of electrons and suggested that all matter has wave properties. (wikipedida)
  • Ernest Schrodinger

    Ernest Schrodinger
    Ernest created the first wave equation for electron movements.
  • Otto Hahn

    Otto Hahn
    Otto discovered nuclear fission.
  • Glen Seaborg

    Glen Seaborg
    He discovered plutonium and all further transuriam elements through element 102.
