Don't forget Alpha Chi Sigma (known as AXE). It is a national co-ed professional chemistry fraternity. My boyfriend is a member at Syracuse University!
They have this really funny shirt that says: (front) Chemists do it on a table...(back) Periodically (with a periodical table on the back).
The site says there have been 90 chapters chartered with 50 active. It was founded in 1902 at the University of Wisconsin! Although they are a professional fraternity, they also operate as a social organization. At Penn State, they have a house!
