Noble gases are the group 0 elements and are all considered as the unreactive non-metal gases. Their application relies upon their low density, inertness, and non-flammability. In comparison to other elements, the noble gases are inert, that is, they are excessively unreactive.
Generally, when the elements react, their atoms complete their outer shells by gaining, losing, or sharing electrons. The noble gases atoms already possess complete outer shells, thus, they do not possess the tendency to gain, lose, or share electrons.
