(a) Interpretation: The most electronegative element of group 6 A needs to be determined. Concept introduction: The group 6A elements show variation from non-metals to metals down in the group. The first element of the group 6A is oxygen with 6 valence electrons. The group 6A is a combination of non-metal, metalloid and metals. The first element of the group 6A is oxygen with 6 valence electrons. Here oxygen and sulfur are non-metals, selenium and tellurium are metalloid and polonium is the only metallic element of group 6A.
