In this unit we are going to investigate how and why atoms bond together to create compounds. We will start with a laboratory activity where you will create two different non-metal gases and determine some of their physical and chemical properties. You should then watch the video "Introduction to Bonding and the Octet Rule" (12 minutes and 21 seconds) which will prepare you for our classroom discussion and future activities. As always, please make sure your notes on the video are hand-written and complete so I can check them at the beginning of the next class.

The first video above introduced examples from the lab that were combined together using covalent bonding. We are now going to look at three videos that introduce the idea of ionic bonding and how to determine formulas and names for these compounds.

We will complete a classroom activity where you will build 21 molecules using a molecular modeling kit (ball and stick models). After that you should watch the instructional video about Covalent Prefixes (10 minutes and 50 seconds).

Here is a summary of the two major types of bonding we have explored (8 minutes 49 seconds). We will also complete a third laboratory investigation where you will heat samples of chemicals to determine the relative strengths of the chemical bonds between ionic, covalent and hydrated crystalline solids.

Here is a pdf of a concept map to complete for homework. It includes all of the types of chemical bonding we have discussed in class.

Here is a pdf of the rubric for your flipbook project.

Your assignment is to make a flipbook (A flipbook shows motion, as you flip through a flipbook, motion is depicted. See me for examples. ) that shows the behavior of atoms as they bond according to the models that we have discussed in class. You should be creative and tell a story about how the atoms meet and become a compound. The more detailed your flipbook is, the better your grade will be. On the last page of the flipbook you should write at least a one paragraph description of what your flipbook depicts.

You must come in after school or at lunch to select which compound your flipbook will illustrate.

It is highly recommended that you use a computer drawing program of some kind to complete this project. Use of color, by using a color printer or colored pencils/markers is required. Sheets of paper or index cards should be cut into a handy size, not full sheets. Bind the final flipbook together with a rubber band or a big paper clip (I have plenty of these to loan you).
