History of The Atom

  • John Dalton

    John Dalton
    In 1803 Dalton proposed the "Atomic theory." His description of an atoms as small round balls. John Dalton is best known for his studies in color blindness.
  • J J Thompson

    J J Thompson
    Thompson said that atoms are posotivley charged and electrions embeded inside. His model looked like a berries in it. J J Thompson also discovered the electron and won a nobel prize for physics in 1988.
  • Hantor Navaoka

    Hantor Navaoka
    The Nacaoka model was discovered by him. His model had a large ball in the middle and a posotive charge It kind of looked like planets revolving around the sun.
  • Ernest Rutherford

    Ernest Rutherford
    His modle of an atom was "mostly empty space and electrions that orbit around the nucleus. Rutherford also identefied particles of the nucleus as posotive charges of matter.
  • Niels Bhor

    Niels Bhor
    He thought an atom would be in shells and move around randomly. He had a theary that electrons didn't spiral into the nucleus. Niels Bohr went to the University of Copenhagen.
  • G N Lewis

    G N Lewis
    The Lewis model atom was discovered by G. N. Lewis. His atomic model became known as Lewis Langmuir Octet. Lewis also contributed to studies in bonding and atomic structure.
  • James Chadwick

    James Chadwick
    His description of an atom is the same description we use today. He thought that they would be protons and nuetrons that orbit randomly. He also proved that the nuetron did exist.
