Question

Element of group 16 (except polonium) are called chalcogens because (A) these elements, particularly sulphur and oxygen, are present in many metallic ores, mainly as oxides and sulphides (B) a large number of acids contain these elements, particularly sulphur and oxygen (C) these elements mainly form anions (D) these elements exist in different allotropic forms

Elements of group-16 (except Po) are called chalcogens i.e. ore forming elements since these elements are present in many metallic ores in the form of oxides and sulphides.

Q. Element of group 16 (except polonium) are called chalcogens because

these elements, particularly sulphur and oxygen, are present in many metallic ores, mainly as oxides and sulphides

a large number of acids contain these elements, particularly sulphur and oxygen

these elements mainly form anions

these elements exist in different allotropic forms
