What is a chalcogen?

A chalcogen is an element in group 16 on the periodic table. This includes oxygen, sulfur, selenium, tellurium, polonium, and livermorium. This name comes from the Greek word meaning “copper-former,” and has its origins in the fact that some of these elements tend to coordinate to metals to form compounds with metals in ores.
