This consists of two parts (and a solution, which is linked below under "Related Resources", but for which you will need a faculty privileges): a primer for students (best if handed out prior to class so that students can read it beforehand, or delivered in pre-lecture format) and a worksheet. The worksheet is designed to be done in small groups with assistance from an instructor. In very large classes, in which the instructor cannot circle amongst the groups, the instructor can work through each example after the groups have a few minutes to work the problem on their own. 

This is an interactive Challenge in which students have to find others in the room with whom they "match" as a hard or soft acid or base. It brings to life the way inorganic chemists think about HSAB. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games.

This Challenge trains student to find inconsistencies in a molecular-orbital diagram. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games. You can pick and choose Challenges from our Web site to increase active learning in your classroom, and we ask that you contribute creative Challenges of your own to give a head start to teachers at other colleges and universities!
