The Noble gases were known as inert gases because it was believed that they were completely unreactive. This is no longer true as scientists have discovered compounds containing noble gas elements.
Inert gases can also be called noble gases. An example is Helium.

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.
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).
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 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).
non-reactive with other substances. The term inert means non-reactive. We refer to gases as being chemically inert if their atoms don't combine with other atoms in chemical reactions.
Noble gases are also known as inert gases because it takes extreme conditions for them to react with any other element, including themselves.
