Question

What are chalcogens?

What is the meaning of the term ‘chalcogen’?

Answer 1

Large numbers of metal ores are oxides or sulphides. Hence, group 16 elements are called chalcogens, or ore-forming elements.

Answer 2

1. Chalcogens are the elements of Group 16 in the periodic table: oxygen (O), sulphur (S), selenium (Se), and tellurium (Te).
2. They are called ore-forming elements.
3. This name comes from their ability to form many metal ores, mainly as oxides and sulphides, such as Cu₂O, Ag₂S, and FeS.
4. These elements commonly occur in the earth’s crust as ores, hence the term chalcogen meaning "ore-forming" elements.
