Presentation Transcript

  1. Discovery of the Electron, Models, and Theories. Andrew, Anthony, Cody

  2. JJ Thompson • Born 1856, England; Died 1940 (age 83) • Won Nobel Prize (1906) • Made great inquirers about the atom’s smaller particles • Concluded atoms were divisible based on his work

  3. JJ Thomson • Experiments dealt with cathode rays • Biggest parts in discovering the electron • Link to more on his experiment • Thomson's Experiment

  4. Thomson’s Model

  5. Robert Millikan • Born 1868, Illinois; Died 1953 (age 85) • Won Nobel Prize (1923) • Discovered charge of electron • Oil-drop experiment

  6. Robert Millikan • Weight-to-charge ratio

  7. Niels Bohr • Born in 1885, Denmark; Died 1962 (age 77) • Won Nobel Prize(1922) • Did work on quantum theory • Made model of atom

  8. Niels Bohr • Used different theories & structures to create atomic model • Model had electrons orbiting around nucleus

  9. Niels Bohr

  10. Louis de Broglie • Born 1892, in France; Died 1987 (age 94) • Won Nobel Prize (1929) • Wave nature of electrons • All matter has wave properties

  11. Werner Heisenberg • Born 1901, Germany; Died 1976 (age 74) • Won Nobel Prize (1932) • Creator of quantum mechanics • Published paper on model of nucleus

  12. Werner Heisenberg

  13. Erwin Schrodinger • Born 1887 in Austria; Died 1961 (age 73) • Won Nobel Prize (1933) • Worked on quantum theory • Looked at electron orbit

  14. Erwin Schrodinger • Important work on wave mechanics • Made quantum Model

  15. Bohr’s Model • Hydrogen only • Electrons orbit around nucleus • Disproved by quantum mechanical

  16. Bohr’s Model

  17. Quantum Mechanical Model • Made by Schrodinger • Depicts electron movement • Works with all elements

  18. Quantum Mechanical Model

  19. Cathode Experiment • Thomson's Cathode Ray Experiment

  20. Oil Drop Experiment • http://ffden-2.phys.uaf.edu/212_fall2003.web.dir/Ryan_McAllister/Slide3.htm

  21. Timeline

  22. Correct Theories/Models • Bohr’s model • Broglie’s thesis • Schrodinger’s model • Planck’s quantum theory • Heisenberg’s model

  23. Incorrect Theories/Models • Thomson’s model • Bohr’s Model
