Science 90 - Nov 13 & 14

On Thursday, we learned about periodic trends in terms of electron configuration and how valence electrons,valence levels and ionic charge are easily determined using the periodic table.  We also learned how to draw Bohr models for each of the first 20 elements as well as ions associated with those elements.  Students did the homework on Slide 78 and this was checked on Friday.

We went over the homework on Friday.  Students then had the rest of the class to work on the vocabulary chart, which is due on Tuesday.  This will conclude the unit on Chemistry.   Students also began studying for their exam in this unit, which is scheduled for next Friday.  Their is a review at the end of their notes.  Students can complete that for an extra 5% on their exam.  Take advantage of this opportunity.  It is an easy 5% plus the marks you gain from studying for the exam.
