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
11
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
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?
16
Free choice from Atomic Structure Links
Atomic structure animation 1-11 or The Particle Adventure or Any link from list
