Chapter 5: Electrons in Atoms

5.1 Light and Quantized Energy
Wave nature of light, wavelength λ, frequency ν,
EMR ( electromagnetic radiation), amplitude, crest,
trough, electromagnetic spectrum, (speed of light) c = λ ν
Particle nature of light, quantum Equantum= h ν,
Planck’s constant h = 6.625 x 10-34 J, photoelectric effect, Ephoton = h ν,
Atomic emission spectra,

5.2 Quantum Theory and the Atom
Bohr model of the Atom, energy states of hydrogen, ground state,
hydrogen line spectrum, ΔE = Ehigher energy level – Elower energy level = Ephoton = h ν
The Quantum Mechanical Model of the Atom, electrons as waves, deBroglie, Heisenberg Uncertainty Principle, Schrodenger, orbital vs orbit, probability map, principal quantum numbers, principal energy levels (1-7), energy sublevels (s, p, d, f)

5.3 Electron Configurations
Ground state electron configurations, aufbau principle, Pauli Exclusion Principle ( ↑ ↓ ) , Hund’s rule, orbital diagrams and electron configuration notations, Valence electrons, Lewis, electron dot structure

  Homework
Section 5.1 Light and Quantized Energy
  1. 11/1/2017 Wave Mechanical Lab - complete and turn in on Friday
  2. 11/1/2017 VIDEO LINK - How to do this lab. If you were in class today, you can skip to approximately 6 min and watch the last 2.5 min only for further directions.
Section 5.2 Quantum Theory and the Atom
  1. 11/3/2017 Write detailed Cornell Notes for pages 127-128. Any similar style that requires summary at the end may be used instead, but check with me first.
  2. 11/3/2017 LINK - PhET animation showing interactive animations of the first 12 element's as Bohr atoms and modern theory of how atoms are constructed
  3. 11/3/2017 LINK - PhET animation used in class on Friday to show electrons hitting atoms who then give off one or two photons of light
  4. 11/3/2017 LINK - PhET animation used used in class on Friday showing frequency of photons vs wavelength of photons.
  5. 11/6/2017 Follow PDF link for directions to this homework, p127-130 using modified Cornell Notes as shown at this link. You must format your notes as shown at link.
