Noble gases are chemically stable because they have completely filled electron orbitals. They generally have 8 valence electrons (helium has only 2) and therefore have a stable electronic configuration.

Means their last orbits are duplet{2} or octet{8}.

What do noble gases form?
Noble gases are stable in nature. They are placed in group-18.
What is the group number for elements that have a stable number of electron spin their outer energy level?
The inert or noble gases have a stable full outer shell of electrons which is why they are so unreactive.
What is the main characteristic that all the noble gases have in common?
the noble gases have octet configuration ie they have 8 electrons in their outermost shell ,so they are stable
Why do noble gases rarely form bond with other atom?
the nobel gases are already stable, with full octets of valence electrons
Why are noble gases stable and unreactive?
Noble gases are stable because they have a complete outer shell - that is, eight valence electrons. Other elements react in order to gain or lose valence electrons, but noble gases are satisfied.
Why is a noble gas inert?
Noble gases have a stable electron configuration. So they are less reactive.

What are noble gases famous for?
Being extremely stable. Noble gases have full valence shells.
What is the biggest characteristic about noble gases?
They are stable.
Is sulfur stable?
No, the only stable elements that are by themselves are the noble gases.
Why do noble gases rarely form bond with other atom?
the nobel gases are already stable, with full octets of valence electrons
Which family is the most stable elements?
The noble gases (aka inert gases) are the most stable elements.
Why are noble gases stable and unreactive?
Noble gases are stable because they have a complete outer shell - that is, eight valence electrons. Other elements react in order to gain or lose valence electrons, but noble gases are satisfied.
Which group of elements is very stable and nonreactive?
The class of noble gases (Helium, Neon etc. in group 18) There are two groups that come to mind when talking stability: the noble gases and the coinage metals. The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are very chemically stable and do not readily form compounds. Note that although Radon is chemically stable, it's not stable from a nuclear standpoint and will decay (but it is not reactive in the chemical sense). The coinage metals (such as gold, silver, and copper) are very unreactive. Note that the further an element is from Au on the periodic table, the more reactive it is (obviously the Noble gases do not follow this trend).
What does noble gasses mean?
Noble gases have completely filled octet. They are stable.
