Answer:
D
Explanation:
Noble gases do not have free valence electrons. They have complete octet or dublet Structure
Statement that explains the inertness of the noble gases is D:the outermost shell has an octet of electrons, except for which has two electrons.
- The inertness of noble gases can be attributed to the presence of 8 electrons in their outermost shell. They have octet of electrons.
- Since their outermost shell is completely filled, they have already attained stability reason for their chemical inertness.
Therefore, there is little tendency by them to accept or donate electrons
