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.

Being extremely stable. Noble gases have full valence shells.


What aren't noble gases reactive?

Noble gases have a full outer shell of electrons, making them stable and non-reactive. Their electron configuration is already at its most stable state, so they do not easily form bonds with other elements. This is why noble gases are often called inert gases.

Which group of elements is very stable and nonreactive?

Noble gases are the group of elements that are very stable and nonreactive due to their full outer electron shells, which gives them little tendency to gain, lose, or share electrons to form chemical bonds.

Why is the noble gases the most stable?

Their valence shells are completely full, so they are least likely to be reactive and are thus most stable.
