Chemistry
State why noble gases are unreactive while atoms of elements other than noble gases are chemically reactive.
Answer
Noble gases are unreactive because they have stable electronic configuration i.e., their outer most shell is complete and are stable hence they do not react. On the other hand elements other than noble gases have unstable electronic configuration i.e., their outermost shell is incomplete and they lose or gain electrons in order attain a stable state.
