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: Use your phone to look up chemical formula for the vitamin you wrote about during the lat class. Also find the structural formula for your vitamin. Record both in your notes
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: HL 6: Ionic and Metallic Bonding/work on your science fair paper/project
INFORMATION PRESENTED IN CLASS:
Students completed the bell ringer by writing the chemical formula and the structural formula for their chosen vitamin in their interactive notebook.
We then discussed how the the structural formula is how the molecule looks, while the chemical formula contains all the parts of the molecule. We noted that none of the vitamin molecules would be possible if the various elements could not bind together to make the compounds.
Students received HL 6, which can be found below:
