Concept explainers
(a)
Interpretation:
The reason of more electronegative nature of oxygen than sulfur should be explained.
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 reason for the formation of long Snchains by Sulfur which is not possible in O atom should be explained.

How can you reconcile this statement with your answer to part (A)?arrow_forwardUntil the early 1960s the group 8A elements were called the inert gases; before that they were called the rare gases.

(b) What discovery triggered this change in name? (c)What name is applied to the group now?arrow_forward
