Atomic Model

  • 400


    Democritus believed that all matter considered of extremely small particles. He talked people into believing him.
  • 402


    Aristotle thought all substances were built u from four elements- earth, wind, water, and fire
  • John Dalton

    John Dalton
    John Dalton pictured atoms as little indestructible particles with no internal structure. His explanation was wooden spheres to represent the atoms of different atoms.
  • Niels Bohr

    Niels Bohr
    This man suggested that electrons travel around the nucleus in definite paths. He also stated that electrons cannot travel in between each path, however they can jump from one path to another.Bohr had adapted Rutherford's nuclear structure Bohr also introduced the idea that an electron could drop from a higher energy orbit to a lower one.
  • Joseph Thomson

    Joseph Thomson
    J.J. Thomson pictured electrons embedded in a sphere in a sphere of positive charged center of an atom, in which negative charges orbit. Some refer to his model as "chocolate chip" because negative charges (chips) and positive charges (chips) are evenly balanced
  • Max Planck

    Max Planck
    He originated the quantum theory.
  • Hantaro Nagoaka

    Hantaro Nagoaka
    He believed atoms looked like the planet Saturn. His model is called the saturnian model because a very massive nucleus ( very massive planet ) and electrons revolving around the nucleus (referring to Saturn's rings).
  • Ernest Rutherford

    Ernest Rutherford
    Ernest pictured all the positive charges in an atomic nucleus was combined in a volume 1/100,000 the size of the atom.
    His experiment was supposed to model alpha particles off the nucleus using the gold foil experiment.
  • Albert Einstein

    Albert Einstein
    Said that light was made up of different particles that, in addition to wavelike behavior, demonstrate certain properties unique to particles.
  • Erwin Schrödinger

    Erwin Schrödinger
    His work leads to the elctric cloud model. He developes a mathematical equation to describe movement in particles.
  • Ernest Marsden

    Ernest Marsden
    Helped Ernest Rutherford with his gold foil experiment.
  • James Chadwick

    James Chadwick
    Confirms Neutrons have no charge.Atomic nuclear cpmtaoms neutrons and positive charge proportions. He used a baryll wam combined with alpha particles.
  • Louis de Brogile

    Louis de Brogile
    Proposes that moving particles like electrons have some properties of waves. This theory set the basis of wave mechanics.
