  1. Chapter 5 #1) Why did Rutherford’s atomic model need to be replaced? Rutherford’s model looked a bit like a solar system

  2. It didn’t explain such things as why elements give off light of specific colors when heated: Example: fireworks, iron

  3. #2) What was the basic new proposal in the Bohr model? That electrons each contain a specific amount of energy as defined by their orbit. The further out the electron orbits, more energy the electron has. Orbits are fixed distances.

  4. #3) What does the quantum mechanical model determine about electrons in atoms? That electrons can only orbit in very specific energy levels, they cannot orbit BETWEEN these levels.

  5. #4) How do two sublevels of the same principle energy level differ from each- other? P-orbital S-orbital The orbitals are shaped differently. Play Chem ASAP from PHschool

  6. #5 How can electrons in an atom move from one energy level to another? BohrModel Bohr Model

  7. #6) The energies of electrons are said to be quantized. Explain what that means. Each electron contains in its orbital a very specific amount or “quantum” of energy. If an electron gains or loses energy, it must change its orbital.

  8. http://center.acs.org/periodic/tools/PT.html Cool periodic table #7) How many orbitals are in the following sublevels? a. 3p sublevel b. 2s sublevel c. 4p sublevel d. 3d sublevel e. 4f sublevel 3 1 3 5 7
