Chalcogen group elements are:

(A) $Se, Tb$ and Pu
(B) $O, Ti$ and Po
(C) $S, Te$ and Pm
(D) $Se, Te$ and Po✓ Correct

Answer: (D)

Solution

The chalcogens are the group 16 elements oxygen, sulphur, selenium, tellurium and polonium. Of the sets offered, only selenium, tellurium and polonium belong entirely to this group; terbium and promethium are lanthanoids, plutonium is an actinoid and titanium is a group 4 transition metal. The chalcogen set is Se, Te and Po.
