Question

Noble gas do not react with other elements because:

• A. they have completely paired up and stable electronic configuration.
• B. their size is very small.
• C. they are monoatomic.
• D. none of these

Answer 1

The correct option is A they have completely paired up and stable electronic configuration.

Noble gas has completely filled valence shell and all the electrons are paired up in each orbit.

Hence, noble gas are very stable because it cannot accept electron or denote electrons (doesn't react with other elements) due to its completely filled and paired up electronic configuration.
