The inertness to chemical reactivity of noble gases is attributed to the following reasons: (1) The noble gases except helium (1s...

By the promotion of one, two or three electrons from filled p-orbital to the vacant d-orbital in the valence shell, 2, 4 or 6 half fil...

Since noble gases have stable electronic configurations, they have no tendency to accept the electron and therefore, have large positi...

Noble gases being monoatomic have no interatomic forces except weak dispersion forces and therefore, they are liquefied at very low te...

liquification of noble gases is quite difficult.It is due to the fact that there are only weak vander waal's forces which hold atoms tog...
