(A) Noble gases (Group $18$ elements) have completely filled valence shells ($ns^2 np^6$,except $He$ which is $1s^2$). Due to their stable electronic configuration,they have very low reactivity and do not form bonds with other atoms under normal conditions. Therefore,they exist in a $monoatomic$ state.
