WebThe inert gases of Group-18 are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). We know that the element in group-18 is neon. The electron configuration of neon shows that the orbit at the end of neon is filled with electrons. Web10. state why are noble gasses unreactive while atoms of elements other than noble gas are chemically reactive Answer: The atoms of elements other than noble gases are unstable because: They have unstable electronic configuration, i.e. their outermost shell is incomplete. They can lose, gain or share electrons and are chemically reactive.
