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: Complete the five questions from the top of the handout with AT, NT or ST.
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 7/work on your science fair paper/project
INFORMATION PRESENTED IN CLASS:
Students completed questions 1-5 on the handout below, discussing why they chose the answers they did.
HL 8. On your OWN paper, answer questions 6-13, placing ONLY the answers that would correctly complete each statement on your paper
Students reviewed home learning 7 and received instructions for HL 8, which can be found above.
We also completed note on ionic and metallic bonding. Remember, if you missed some of the notes, you can find the entire power point on My Big Campus. You can also find the shortened movie version of the notes on this site (see last class blog notes).
We then practiced recognizing bond types. The handout can be found below. Complete and place in your notebook.
Students continued to practice making ionic bonds on their personal devices. Click the link Ionic Bonding to practice this skill.
Students also completed an exit slip on bonding.
Don't forget, projects are due in class on Monday!
