טקסט Storyboard

  • I believe the universe has empty space and atomos (atoms) are invisible!I think atomos are as solid and the same throughout!I believe in ideas instead of experiments.
  • Democritus 460 bce - 370 bce
  • Dalton 1766-1844
  • Let me use air pressure and water vapor to devise my theory.All matter is made up of atoms!elements are composed of identical atomos.
  • Atomos have charges.The particle has an electric current.electrons float in a sea of charges.
  • J.J. Thompson 1856-1940
  • Ernest Rutherford 1871-1937
  • I will test the plum pudding model J.J. Thompson had.I will shoot tiny positively charged particles out of a particle gun, toward a thin sheet of gold foil.I will detect reflected particles of various angles.
  • Niels Bohr 1885-1962
  • electrons occupy specific or exact energy levels.energy levels are specific distances from the nucleus.There are specific amounts of energy that are required to move electrons to the next energy level.
  • electrons do not stay in a certain orbit.Let me model a wave equation to identify properties of a wave as well as a partticle.The wave equation can predict the probable location of electrons.
  • ErwinSchrödinger1887-1961
