Electrons and Energy Levels http://www.colorado.edu/physics/2000/quantumzone/bohr.html

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.

3/1/16 HW Need: textbook Assignment: Read p 113-115. 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

Check out Bohr’s model for Oxygen on atomic timeline

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.

3/2/16 HW Need: periodic table, today’s drawings of atoms Assignment: complete, practice, or study drawings and periodic table for atoms 1-10, 11, 17. Due : Friday 3/4/16 Meet in 309 computer room tomorrow Bonus: fill in atoms 12-16, 18, 19, 20,

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

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

4.2 Review of Atomic Structure Please log in Internet – BRMS – Rountree – links – Atomic Structure Last link – The Atom – please wait for more directions Mute speakers

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

The Atom Read and THINK Interact and THINK “test”

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

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?
