Students: here is Paul Anderson's video, as shown in Wednesday's class, explaining the concept of the mole with helpful illustrations:
Student should use this video to complete a worksheet given in class, which is also available online HERE.

NOTES: ELECTRON CONFIGURATION
Students, here is the Power Point for the Unit 2 notes on electron configuration, orbitals, models of the atom, and rules for electrons:
Students should use this along with the previous section of Notes to complete the Study Guide for next Thursday's test (10/18), and along the way make sure that everything in the Study Guide does, in fact, appear in their notes.

HONORS: THE PERIODIC TABLE
HONORS STUDENTS: Here are the Power Point Notes on the Periodic Table given in 1st period.
Inside you will find information about the structure of the periodic table, how to read it, how to calculate molar masses, isotopes and ions, ionic and covalent bonds. This needs to be completed in your Composition Book this week, as we are moving on to other material.

VIDEO: FLAME TEST
If students were absent on Monday, Oct. 21st, they did not get to see the actual lab where we performed a 'flame test' on various ionic compounds.
Here is a video that shows much the same sort of observations students made on Monday. Unfortunately, it is not practical to 'make up' this particular lab. Watch the video, students, and compare it with observations that students who attended were able to make in order to understand the material:

REGULARS: SATURDAY SCHOOL
Is it an opportunity or a punishment?
That's up to you, students.
Some of the students in my Regular Chemistry classes have received a YELLOW CARD which assigns them to Saturday School, where they will work on a package of remedial work.
Saturday School for Regulars will occur on Sat., Oct. 26th.
It is the responsibility of students to have parents contact the instructor to make an alternative arrangement in the event of a conflict.

VIDEO: COVALENT AND IONIC COMPOUNDS
Both Honors and Regulars are doing activities in October that require them to distinguish between covalent and ionic bonding. This video from Paul Anderson is a master teacher's original way of teaching how to use a periodic trend (electronegativity) and the octet rule to determine whether a compound is ionic, polar covalent or non-polar covalent.
