Explain why the atoms of noble gases have chemical stability
Because they are full and happy, meaning they are surrounded by a full octet( 8 electrons)
They are the most stable due to having the maximum number of valence electrons their outer shell can hold.
For a compound to be stable, its outer most valence shell must be completely. This means it must have 8 electrons in the outer most shell. Since the elements of group 18 have their outermost shells filled with 8 electrons they are stable.
The outermost shell of any atom is called the valence shell that's the way I understand it. Because each of the noble gas elements has 8 electrons in their valence shells, and are largely nonreactive because their shells are filled, stability implies nonreactive. if you look at the halogens, however most notably fluorine, which has 7 valence electrons, it really wants to satisfy its otctet and its high electronegativity value explains this propensity to gain an extra electron as well as its high re activity.
