Noble gases do not react with other elements because

1. (a) They are monoatomic
2. (b) They are found in abundance
3. (c) The size of their atoms is very small
4. (d) They are completely paired up and stable electron shells

Correct answer: (d) They are completely paired up and stable electron shells

Solution

Noble gases have completely filled and stable electron shells, making them chemically inert and unlikely to react with other elements.
