### 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
 10/18/2018 Mod Cornell Notes Ch 5.1 p 117 - 119 (1 blue, 2 red sections), one page minimum 10/19/2018 mod Cornell notes p. 120-121 (include summary of example problem p121) - ADDED TO Cornell Notes Ch 5.1 p 117 - 121 (1 blue, 2 red sections), one 1/2 page minimum. (10 pts FOR both combined together) 10/22/2018 VIDEO LINK - how do today's practice probloems, which are very similar to your homework. Given frequency calculate wavelength, or given wavelength calculate frequency. 10/22/2018 p 121 1-4 (for #1,2, & 4 show calculations, for #3 give explanation) 10/24/2018 p 126 7,8,9,10, & 12 (this is a matching of a,b,c to 1,2,3) (5 pts) 5/9/2019 VIDEO LINK - Tyler DeWitt - Ionic vs Molecular 5/9/2019 VIDEO LINK - What Happens When Stuff Dissolves
##### Section 5.2 Quantum Theory and the Atom
 10/29/2018 Cornell Notes p. 127 - 130 (2 Red sections, 3 blue sections), vocab (5 pts) 10/30/2018 Wave Mechanical View of the Hydrogen Atom - LAB 11/1/2018 LINK - animation used in class today to help visualize why electrons in the ground state "jump" to higher energy levels and then return to the ground state. 11/5/2018 NO HOMEWORK BUT What about your notebook that is due on Thursday? Look on my home page for link of how to do it. Don't wait until Wednesday night at midnight!!!! 126 points on the line!!!!! 5/17/2019 LINK - for Mass % & Molarity Lab Sheet 5/20/2019 Complete Mass% & Molarity Lab as shown in class today - 20 pts
