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