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) and are known as inert gases.

Noble gases are called inert gases because they rarely react with other elements to form compounds. They have a full outer electron shell, making them stable and less likely to form chemical bonds with other elements. This inertness gives them low reactivity under normal conditions.
Noble gases are also called inert gases because these gases were not known to form any chemical compounds until about fifty years ago.
Noble gases have completely filled orbitals. They are stable and chemically inert (non-reactive).
The inert gases can also be called noble gases due to their stability and lack of reactivity. These gases include helium, neon, argon, krypton, xenon, and radon.
The most distinctive property of noble gases is that they are chemically inert, which means they have a full outer electron shell and do not readily react with other elements.
The noble gases were once called inert gases because until about 1960, no compounds of them had been discovered.
Noble gases are also known as inert gases because they are generally unreactive due to their full outer electron shells.
Noble gases are called inert gases because they are very stable and unreactive due to having full outer electron shells. This stability makes them unlikely to form chemical bonds with other elements. The term "noble" comes from their perceived similarity to noble metals, which are also stable and unreactive.
