Monday Monday
AP, Honors, and Regents Thanksgiving Vacation assignments and homework will be posted late tonight/tomorrow. The assignments (and for Regents and Honors, the homework also) will be graded and count towards your second quarter average. ALL WORK MUST BE EXPLICITLY, CLEARLY, and NEATLY SHOWN on these assignments (or you will not receive much credit). Assume that you are writing for someone who has NO knowledge of chemistry and physics. Make sure that your work is done and handed in during class on our return from vacation on Monday.
Honors: we traversed the Periodic Table and learned of the various group names and some physical/chemical properties of the groups/families of elements. We discussed properties of metals, nonmetals, and semi-metals/metalloids. We then introduced the Periodic Trends that we will completely explain over the next few classes. These lessons are the MOST IMPORTANT lessons of the ENTIRE year. Take excellent notes. Then, copy them again and again until they are COMPLETELY intuitive and internalized. If you know the material in next few lessons, then you will truly understand the HOW and WHY of chemistry.
Regents: We reviewed our last test, emphasizing the importance of DRAWING things out (Bohr Models of atoms or ions) and showing calculations (Zeff) and looking things up on the Reference Tables as a check on your knowledge of periodic trends. We then discussed individual groups of elements. We should be able to close out the unit tomorrow.
AP: we finished electron affinity and then we looked at physical and chemical properties down a group and across a period.
We also did some descriptive chem reactions of metal oxides in water or in acid and then nonmetal oxides in water or in base.
We may be able to close out the unit tomorrow. Either way, our exam on Day 6 will be on the material covered through tomorrow.
