Thank you to Jane Johnson, Diana Basham and Geni Slosser for volunteering today. Attached is some student work.
Lewis structures model the valence electrons of atoms. The attached document shows what the Lewis structures look like for the atoms we are concerned about. Also attached is some vocabulary we have been using the last few days
Students should understand the basic parts of an atom (no need for quarks) and be able to figure out the number of protons, neutrons and electrons from the periodic table. See finding neutrons to see how to find the number of neutrons.
This presentation gives a basic overview of the parts of an atom.
We spent the day preparing for the test on Monday.
