(a)
Interpretation:
The metal 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 last element of group 6A.
(b)
Interpretation:
The most abundant element in the human body of group 6A needs to be determined.

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 last element of group 6A.
(c)
Interpretation:
The strongest oxidizing agent in the group 6 A needs to be determined.
