Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
Noble gases are called Inert gases because they are nonreactive. Noble gases already have full valence shells so they don't bond with other elements under natural circumstances.
Inert gases can also be called noble gases. An example is Helium.

when an element has 8 electron in outer shell it is said to be inert. inert gases are called noble gases.
All inert gases exist as gases in nature; but today the name inert remain only traditional. The so-called noble gases has known compounds (excepting neon).

Inert gases can also be called noble gases. An example is Helium.
As we all know that noble gases are also called INERT GASES, so the subgroup VIII of GROUP 'A' contains only noble gases and inert gases so helium and neon are also in VIII-A so they are inert gases.

Noble Gases
Inert gases are the noble gases (He, Ne, Ar, Kr, Xe, and Rn). They used to be called the inert gases until Neil Bartlett proved that you could make compounds out of some of them, so they were renamed "inert" gases.
Noble gases are gases and have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and called inert gases.
Noble gases used to be called inert gases because until the 1960's no chemical compounds of a noble gas had been made hence they were believed to be completely inert. Now compounds of argon, xenon radon have been made. These are all very reactive. Compounds of helium and neon have not yet been made.
