Vedclass · Answer

(B) Noble gases like $Ne$ are chemically inert due to their stable electronic configuration and small atomic size.$Xe$ has a larger atomic size and lower ionization energy,allowing it to form compounds with highly electronegative elements like $F$ and $O$.$Ne$ does not form stable compounds like $NeF_2$ because its ionization energy is very high and it lacks vacant $d$-orbitals for bonding.Therefore,$NeF_2$ does not exist.
