Students started the day with a foldable reviewing all the dudes they need to know that influenced the develop- ment of the atomic model. Students tried it out without their notes and realized how little they remembered... and then used their notes to record the information. We also watched a BrainPop about the atomic models to help refresh their memories. Now that they have their foldables made, they can use them to study for Friday's unit test and to study for the SOL.
Next we finished up the notes by discussing periodic trends.
Electro- negativity is how badly atoms want electrons. The most electronegative atoms are Fluorine, Chlorine, and Oxygen. Ionization energy is how difficult it is to remove electrons. It is difficult to remove electrons from atoms that are electronegative.
Atomic radius increases as you move down the periodic table because atoms have more mass, but actually decreases from left to right because atoms are holding on to their electrons tighter (because they are more electronegative).
To finish class students worked on a review sheet for Friday's unit test.
Homework tonight - work on packets and Box J on the Gold Sheet.
If you were absent for the Physical versus Chemical lab, you can make up the majority of it by following the link below and watching YouTube videos of the experiments. You can also just check them out because they are cool.
Open a link in a new tab. In the blue box, look for "Play Games" and "Scatter." You will then need to drag the names to the correct formula. If it disappears, you matched it correctly. Play each set a couple of times until you get really good. You can also use these as flashcards and make up and take tests.
