Atoms and Matter

By laral
  • Isaac Newton

    Isaac Newton
    Suggestion and small solid populace's in movement mechanics universe.
  • Lavoisier

    Provided the formula for the conservation of matter in chemical reactions, and also distinguished between an element and a compound.
  • Couloumb

    Formulated the Coulomb's law, which states that that the force between two electrical charges is proportional to the product of the charges and inversely proportional to the square of the distance between them, one of the main forces involved in atomic reactions.
  • John Dalton

    John Dalton
    Formed the atomic theory, which states that all matter is composed of tiny, indestructible particles called atoms that are all alike and have the same atomic weight.
  • Crookes

    Created the Crookes’ tube and demonstrated that cathode rays travel in straight lines and produce phosphorescence and heat when they strike certain materials.
  • W.K. Roentgen

    W.K. Roentgen
    Discovered x-rays while experimenting with cathode-ray tubes.
  • Becquerel

    Discovered radioactivity when he investigated uranium and other radioactive substances.
  • The Curies

    The Curies
    Discovered radium and polonium when they started to investigate radioactive substances
  • J.J Thomson

    J.J Thomson
    Discovered the electron and developed the plum-pudding model of the atom.
  • Max Planck

    Max Planck
    Originated the quantum theory
  • Albert Einstein

    Albert Einstein
    Postulated that light was made up of different particles that, in addition to wavelike behavior, demonstrate certain properties unique to particles. He also brought forth the theory of relativity.
  • Robert Millikan

    Robert Millikan
    Found out the electric charge of the electron.
  • Ernest Rutherford

    Ernest Rutherford
    Used the results of his gold-foil experiment to state that all the mass of an atom were in a small positively-charged ball at the center of the atom.
  • Neils Bohr

    Neils Bohr
    Stated that the electrons moved around the nucleus in successively large orbits. He also presented the Bohr atomic model which stated that atoms absorb or emit radiation only when the electrons abruptly jump between allowed, or stationary, states.
  • Geiger

    Introduced the first detector of alpha particles and other radiations.
  • Erwin Shroedinger

    Erwin Shroedinger
    Introduced the Shroedinger Equation, a wave equation that describes the form of the probability waves that govern the motion of small particles and how these waves are altered by external influences.
  • Chadwick

    Discovered the neutrally-charged neutron
  • Otto Hahn

    Otto Hahn
    Discovered nuclear fission, in which the nucleus of an atom breaks up into two separate nuclei, while experimenting with uranium.
  • Glen T.

    Glen T.
    Seaborg Isolated and identified elements heavier than uranium, and in the process, added elements number 94 - 102, and 106.
  • Murray Gell-Mann and George Zweig

    Murray Gell-Mann and George Zweig
    Brought forth the idea of "quarks", little bits of matter which when used kind of like building blocks, serve to explain some complex chemical substances.
