Concept explainers
(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.
(b)
Interpretation:
The semimetal needs to be identified in group 6 A.
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.
(c)
Interpretation:
Theradioactive element in 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.
(d)
Interpretation:
The most abundant element on the Earth’s crust 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.
