1. Electrons and Energy Levels

2. 3/1/16 4.2 Atomic Structure Review
Please “change colors” from yesterday and in your notebook correct questions #1-8 p112 using the handout.

3. 3/1/16 HW
Need: textbook
Assignment: Read p Focus on placing electrons into energy levels
Think about oxygen with two energy levels of electrons on the second row of the periodic table; think about oxygen with 6 outer electrons in group 6a
Due: tomorrow

4. Check out Bohr’s model for Oxygen on atomic timeline

5. Drawing Atoms 1-10,11, 17 Please make sure you have a pencil
If you have time please check out the Electrons and Energy levels in the hallway
before class. Check out oxygen atom.

6. 3/2/16 HW Need: periodic table, today’s drawings of atoms
Assignment: complete, practice, or study drawings and periodic table for atoms , 11, 17.
Due : Friday 3/4/16
Meet in 309 computer room tomorrow
Bonus: fill in atoms 12-16, 18, 19, 20,

7. Counting subatomic Particles
Number = # # protons = Atomic # # neutrons = Mass # - Atomic # # electrons = # protons

8. Rules for placing electrons into energy levels
2 electrons maximum for 1st energy level
8 electrons maximum for outer energy level

12. 3/3/16 HW
Need: internet
Assignment: Explore Atomic Structure links for 10+ minutes
Due: tomorrow ( back to 122*) Be ready to share
Unit 4 : Atomic Structure test next week
*Static Electricity Day – playing with electrons – wash hair, don’t condition for maximum electron repulsion

13. The Atom
Read and THINK
Interact and THINK
“test”

14. 2nd to last link PhET Build an Atom
Click on net charge, mass number and check off stable/unstable
Build Neutral and Stable Atoms 1-10 – think about yesterday – atomic number and mass number; think about charge
Check out symbol and games at the bottom

15. Find David’s Whizzy Periodic Table link and click
Click on electron shell
Click on elements 1-21
What energy level were the electrons placed on?
