Here’s the lecture on a couple more periodic trends – electron affinity, ionic radii, and valence electrons. We’ll for real finish the chapter tomorrow! Make a change on the syllabus – review tomorrow, pre-test on Wednesday, and TEST on Thursday.

Here’s the lecture on the first periodic trends – atomic radii and ionization energy. We’ll finish second ionization energy and the rest on Monday. Don’t forget the element videos in vodpod collection below. If you want to see videos on all of the elements, a cool website is periodicvideos.com. Just click on the elements, it’d be a great review!Have a great weekend!

Do you like it better than orbital notation? Since we had a bit of a challenge with the vodcast recording, I dug back in the archives from last year and found this lecture on electron configuration notation, just in case you’d like the review.

Remember, when you write it, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. Make sure you put the dots in the right order. The very end of the vodcast has the slide that compares ionic vs. covalent compounds.
