Week 9 Schedule: Section B

Now that we know that electrons are in orbitals (not orbits!) around the nucleus, that different orbitals have different shapes and energy levels, and that no two electrons can have the same 4 quantum numbers, we will be able to determine how electrons are arranged around any element.  This week we’ll build on this understanding to discuss periodic trends and chemical properties for the elements in chapter 7.

Homework 8 is now posted on Mastering Chemistry.  It is due on Saturday at midnight and will cover all of chapter 6.

Office hours this week will be Wednesday from 2:30-4:00 pm and Friday from 1:00-2:30pm.  Feel free to email me if you’d like to meet but can’t make those times.
