A type of element found in group 16 of the periodic table, which includes oxygen, sulfur, selenium, tellurium, and polonium.
Oxygen is a well-known chalcogen that is essential for life.
Chalcogen → It is formed from "chalcos" (from Greek, meaning copper) and "genes" (from Greek, meaning born of or producing). The term refers to elements that are associated with copper and include oxygen, sulfur, selenium, tellurium, and polonium, which are known for their ability to form compounds with metals.
Think of 'chalcos' meaning copper and 'genes' meaning born of — this helps you remember that chalcogens are elements that produce compounds with metals like copper.
