What do you teach about the f-block?
I like to do the Inorganic Chemistry Top 10 First Day activity by Sheila Smith in which students categorize graphical abstracts from IC by inorganic chemistry subdiscipline. One of those is f-block chemistry. We see f-block chemistry in the abstracts, but I admit that I don't really teach much about how f-block elements compare to the d-block elements that my course centers around. (FWIW, my course is a fundamentals+topics course for senior chem majors who have had p-chem.)
So what are the top 7 things (seems like a good number) that a student should know about the f-block? What LOs do you use to get them there?
(By the way, there was a forum post about this topic in 2008, but VIPEr has changed so much since that time that I thought we could start fresh.)
