Storyboard Tekst

  • Democritus
  • Democritus used the word atomos, Greek for unbreakable, to describe the smallest parts of matter. His is an early atomic theory, though he lacked evidence.
  • History of the Atom
  • Thomson
  • The cathode ray experiment helped Thomson realize that the atom could be divided into smaller parts, including a negatively charged part called the electron.
  • Dalton
  • Five Statements of Atomic Theory, with evidence
  • He theorized that the positive part of the atom was like pudding with electrons embedded in it.
  • All elements are made of atoms that differ from one another. Atoms of the same element are identical. Atoms combine in whole number ratios.
  • Rutherford
  • With the gold foil experiment, Rutherford discovered the small, dense center of the atom and he named it the nucleus.
  • Bohr
  • By studying the spectral lines of hydrogen, Bohr theorized that electrons move at fixed energies, in paths he called orbits. His model described H perfectly.
  • Electron Cloud Model
  • The modern idea of the atom suggests the 90% probability of "locating" an electron in mathematically-determined shapes called orbitals.
