Recent edit to Chalcogen
Hello, and thank you for your recent contribution. I appreciate the effort you made for our project, but unfortunately I had to undo your edit because I believe the article was better before you made that change. Feel free to contact me directly if you have any questions. Thank you! Kevin12xd (contribs) 16:59, 8 July 2015 (UTC)
