Notes on Balancing Chemical Equations and Ionic Nomenclature
Final part for the Chemical Reactions Lab: For 4 rxns from the lab, balance the overall equation AND name the products that were produced. (These 4 complete reactions and the rest of the lab work you did initially should be turned in next Tue/Wed.)
You may earn up to 3 extra credit points for this lab if you complete 3 more reactions and they are correctly balanced, include the compound names, and whether or not the reaction will happen (using solubility rules, we will learn about these next week.)
Naming Booklet As you work through the notes for naming, use the booklet we made in class (directions below if you still need to make one) to start writing down your rules for naming the different types of ionic compounds. Here are the pages to include in your booklet: (Representative Ions--Grps 1-2, 13-18; Polyatomic Ions; Transition Metal Ions.) For each page, list the rules you should follow for naming those types of ions and the exceptions to these rules. We will use the 4th page later, so don't put anything on that page yet.

Weekly Practice 1.2 Due on Monday. (Remember the answer key is in my room if you get stuck)
During class today we will focus on "Periodic Trends" because they tend to change in predictable ways as you move across and down the PT. All of these trends can be explained with Effective Nuclear Charge, so you should not attempt to memorize these. Instead it will help you immensely if you can logically reason how Effective Nuclear Charge is causing each of them to change.
Watch the two videos below which demonstrate periodic trends.
Which periodic trend does this video demonstrate?
This next video is a fake, but it is still worth watching. What periodic trend does this video demonstrate?

We will also model effective nuclear charge in class today and spend some time creating your own analogy similar (but different) to the ones we discussed in class. Here is a good example Led Zefflin Concert Your model or drawing should be self-explanatory, but if you don't feel that all of the aspects below have been covered you can include a short written explanation that discusses how these things are depicted in your analogy and how they affect or are affected by the effective nuclear charge. You can do this on the back of the assignment.
