ESSENTIAL QUESTION: Why do bonds form between elements?
NGSSS: SC.912.P.8.6
BENCHMARK(S):
-Distinguish between bonding forces holding compounds together and other attractive forces, including hydrogen bonding and van der Waals forces.
LEARNING OBJECTIVES: Students will be able to:
-distinguish between ionic, covalent bonds, and metallic bonds and explain how they are formed.
BELL RINGER: Students were given handout and asked to draw the Lewis dot configuration of the valence electrons.
 |
| Write the symbol for each element listed and place the valence electrons around each. This will help you learn which electrons are available to form bonds and to determine the types of bonds that can be formed. |
VOCABULARY: valence electron electron dot structure, octet rule, halide ion, ionic bond, ionic compound, chemical formula, formula unit, coordination number, metallic bond, alloy
HOME LEARNING: work on your science fair paper/project
INFORMATION PRESENTED IN CLASS:
After reviewing the bell ringer, we reviewed home learning 6. B sure to place both the bell ringer and the home learning in your interactive notebook.
Students then viewed the video Dogs Teaching Chemistry on forming bonds. They did a stop and jot as the video played. You can find the video below.

| Use this sheet and the information from the video to help you complete the sheet below. |
 |
| Complete this handout by using the video and the types of bonding handout. Both handouts should be placed in your notebook.
We will complete the topic on bonding when we return from Christmas break.
Have yourself a Merry Christmas!
