Atomic Theory

  • Antoine Lavoisier

    Antoine Lavoisier
    Wrote the Elementary Treatise of Chemistry. The book contained a list of elements, the most recent theories and laws of chemistry and refuted the existence of phlogiston. http://www.famousscientists.org/antoine-lavoisier/
  • Joseph Louis Proust

    Joseph Louis Proust
    French chemist who proved that the relative quantities of any given pure chemical compound’s constituent elements remain invariant, regardless of the compound’s source. Also worked with research in nutrional chemistry. http://www.britannica.com/biography/Joseph-Louis-Proust
  • John Dalton

    John Dalton
    His atomic theory said that elements consisted of tiny particles called atoms. It states an element is pure. All elements are different from each other due to differing masses. A compound is a pure substance due to different. https://the-history-of-the-atom.wikispaces.com/John+Dalton

  • Michael Faraday

    Michael Faraday
    His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis.Contributed to the fields of electromagnetism and electrochemistry,
  • Quantum Mechanical Model

    Quantum Mechanical Model
  • Henri Becquerel

    Henri Becquerel
    He discovered radioactivity and that became the focus of his work.Becquerel was awarded the Nobel Prize for Physics in 1903. http://www.biography.com/people/henri-becquerel-40055
  • JJ Thomsan

    JJ Thomsan
    Thomsan Discoverd the electron in a series of experiments designed to study the nature of electric discharge. One of Thomson’s important experimental programs focused on the nature of positively charged particles these techniques led to the development of the mss spectograph. http://www.chemheritage.org/discover/online-resources/chemistry-in-history/themes/atomic-and-nuclear-structure/thomson.aspx
  • Marie Curie

    Marie Curie
    She is best known as the discoverer of the radioactive elements polonium and radium and as the first person to win two Nobel prizes. https://www.mariecurie.org.uk/who/our-history/marie-curie-the-scientist
  • Max Planck

    Max Planck
    Max Planck was a German theoretical physicist, considered to be the initial founder of quantum theory,Planck thought that energy was made of individual units, or quanta.

  • Ernest Rutherford

    Ernest Rutherford
    Rutherford, Hans Geiger and Ernest Marsden carried out the Geiger-Marsden experiment.The results of this experiment demonstrated the existence of the atomic nucleus and became a part of the Rutherford model of the atom. http://www.sciencekids.co.nz/sciencefacts/scientists/ernestrutherford.html
  • Robert Milikan

    Robert Milikan
    He discovered the accurate determination of the charge carried by an electron.He also proved that this quantity was a constant for all electrons,demonstrating the atomic structure of electricity. http://www.nobelprize.org/nobel_prizes/physics/laureates/1923/millikan-bio.html

  • Albert Einstein

    Albert Einstein
    One thing Einstein is best known for is his E=mc^2 formula.Einstein applied the general theory of relativity to model the large-scale structure of the universe. He delveloped the general theory of realitivity. http://www.biography.com/people/albert-einstein-9285408
  • Lisa Meitner

    Lisa Meitner
    Discovered a new element protactinium. She work in the field of atomic physics she wrote and served on the United Nations Committee on atomic energy.
  • Ernest Schrodinger

    Ernest Schrodinger
    Schrödinger articulated the movements of electrons in terms of wave mechanics as opposed to particle leaps. He provided a way of thinking that would be incorparted into thousands of papers becoming an important part of quntam therory. http://www.biography.com/people/erwin-schrdinger-9475545#wins-nobel-prize
  • Louis DeBroglie

    Louis DeBroglie
    DeBroglie made groundbrreaking contributions to quantum theory.In his 1924 thesis he said the wave nature of electrons and suggested that all matter has wave properties. http://www.famousscientists.org/louis-de-broglie/
