History of the Atom

  • John Dalton`s Model

    John Dalton`s Model
    his model proposed the statement that atoms are the smallest particle of an element, that atoms of different elements have different masses and that they are solid, indestructible units.
  • John Dalton

    John Dalton
    Was an English chemist, meteorologist and physicist, born in September 6,1766 and died on July 27, 1844, he is best known because of his work on the atomic theory
  • Plum Pludding Model

    Plum Pludding Model
    Thomson said than an atom was a large positively charged body, that contained small, free floating, negatively charged electrons.
  • J.J. Thomson

    J.J. Thomson
    English physicist, credited for finding the first evidence of isotopes of a stable element, won the Nobel Prize in Physics in 1906, born on December 18, 1856 and died on August 30, 1940
  • Rutherford Gold Foil Experiment

    Rutherford Gold Foil Experiment
    Stated that there is a small dense positively charged nucleus surrounded by empty space and small negatively charged electrons.
  • Ernest Rutherford

    Ernest Rutherford
    Was a New-Zealand physicist and chemist who is referred as the father of nuclear physics, born in August 30 1871 and died in October 19, 1937
  • Rutherford Model

    Rutherford Model
    Described the atom as a tiny densed, positively charged nucleus in which nearly all the mass in concentrated at which negatively charged electrons would circulate
  • Ernest Rutherford

    Ernest Rutherford
    Was a New-Zealand physicist and chemist who is referred as the father of nuclear physics, born in August 30 1871 and died in October 19, 1937
  • Bohr Model

    Bohr Model
    Said that the atom is small, has a positively charged nucleus surrounded by electrons that travel in circular orbits but that only these orbits for which the angular momentum of the electrons were in integral multiples of h/2pi were allowed
  • Niels Bohr

    Niels Bohr
    was a danish physicist who made great contributions on atomic structure and quantum mechanics, reeceived the nobel prize for physics in 1922, born in October 7, 1885 and died on November 18, 1962
  • Quantum Mechanical Model

    Quantum Mechanical Model
    Based on quantum mechanics, each electron is thought as a negatively charged cloud, believed that electrons occupy all the space in the atom at different rings and that an atom consists of energy levels, neutrons and protons.
  • Erwin Schrodinger

    Erwin Schrodinger
    whas an austrian physicist who made fundamental contributions in the field of quantum theory, and famous for his example known as Schrodinger`s car, born August 12, 1887 and in January 4, 1961
