Noble gases do not react with other elements because

Options

A. they are monoatomic
B. they are found in abundance
C. the size of their atoms is very small
D. they are completely paired up and have stable electron shells

Answer

D

Explanation

In general , noble gases are not very reactive, Their chemical inertness is due to the fact that they have completely filled `ns^(2)np^(6)` electronic configuration of their valence shells. The other reasons are very high ionisation enthalpy and almost zero electron affinity.
