Presentation Transcript

  1. Electron Cloud • Electron Configuration: how the electrons are arranged within the electron cloud • Bohr: Published the idea that electrons are energetic particles that exist on distinct energy levels • Schrodinger: Revised the Bohr model to include the ideas of energy sublevels, wave nature, and much more...

  2. Periodic Table Labeling S block: blue d block: red P block: yellow f block: green

  3. Moore’s Motel • Managers: • Aufbau: Each room/bed on the lower floors must be occupied before moving to a higher floor. • Pauli: A maximum of two guests may occupy a bed. Guests must sleep head to foot. • Hund: Single guests must occupy separate beds in a room. No pairing occurs unless no empty beds exist.

  4. Moore’s Motel Rooms available: S: Single room, has only one bed (sleeps 2) P: Prestige room, has three beds (sleeps 6) D: Deluxe room, has five beds (sleeps 10) F: Fabulous room, has 7 beds (sleeps 14)

  5. The Analogy • Floors = energy levels (1-7) • Rooms = sublevels (s,p,d,f) • Beds = orbitals (x,y,z axis) • Guests = electrons • Head to foot = spin of electron (clockwise and counterclockwise)

  6. Using the periodic table: • Start with Hydrogen at the 1s position. • Continue following the blocks of the table until reaching the element in question.
