Presentation Transcript

  1. In 1913, Niels Bohr developed a model of the atom where: • electrons move in paths around the nucleus • these electron paths are called energy levels

  2. Bohr Models and Energy Levels

  3. Electron Orbits

  4. 10. The Bohr model of the atom • The small circle represents the nucleus • The p+ stands for protons (positive charge) • the n0stands for neutrons (no charge) • The circles around the nucleus represent energy levels • The e- stands for electrons (negative charge)

  5. Bohr Models of Atoms

  6. Steps to drawing the Bohr model Determine the number of protons, electrons, and neutrons. (A.P.E. M.A.N.) Draw nucleus. Fill in electrons starting from the inner energy level. 1st Level: 2 electrons 2nd Level: 8 electrons 3rd Level: 8 electrons

  7. Atom with electron orbits

  8. P = protons • N = neutrons • - = electrons
