Lewis Dot Diagrams

Here is some additional review material for Lewis Dot Diagrams.  With break coming so soon, I know some review help will probably be in order for January, and now you're ready to go!

Electron Dot Structures (aka Lewis Dot Diagrams)

Also, here are some good images:

Atoms and Compounds:

Polyatomic Ions:
Nitrate and Carbonate (remember: each one has a negative charge (CO3 -2 and NO3 -1)...it's just not written in)

Sulfate:    Ammonium:



Review Material for Next Test

Reminder: Your next test is coming at the beginning of next week!  It will cover the material we have  talked about from Chapter 13.  Here are the test dates:

1st hour: Monday 12/12
5th hour: Tuesday 12/13

Here are the topics we have covered, and a few resources to help you study!

• Electron Orbital Diagrams
• Electron Configuration
• History of atom models and scientists’ contributions to our understanding of the atom: Democritus to Schrodinger
• The 3 Rules for filling orbital diagrams
• Orbital shapes
• Noble Gas Configuration
• Quantum Numbers
• Creation of electromagnetic radiation (light and “invisible light”)
• Vocabulary: quantum, atomic orbitals, energy levels, quantum mechanical model, sublevels, atomic emission spectra
