Group 16 elements (except polonium) are called chalcogens because
A.these elements, particularly sulphur and oxygen, are✓ Correct
B.a large number of acids contain these elements,
C.these elements mainly form anions
D.these elements exist in different allotropic forms
Explanation
Most of the ores of brass or copper contain the oxides or sulphides. Apart from that, it contained the traces of selenium and tellurium. These elements are found in the Group VI and therefore, it is called chalcogens Thus, the correct option is (a) these elements, particularly sulphur and oxygen, are present in many metallic ores mainly as oxides and sulphides. Thus, the correct option is (a)
