Noble gases are inert for a simple reason - Their outer electron shells are already full. Generally, the more empty the outer electron shell, the more reactive the element.
Helium has two(2) electrons, and is thus full, all the other noble elements has eight (8) electrons in it's outer electron shell, so they are also full.
*And krypton is not green, but colorless, and forms white crystals when solid.*
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 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 have completely filled electronic configuration and hence they are chemically inert (they generally do not form bonds).
Noble gases have completely filled electronic configuration and hence they are chemically inactive / inert / do not form bond with other elements.
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.

Because before about 1950, the noble gases were not known to form any chemical compounds.
Noble gases have completely filled electronic configuration and hence they are chemically inert (they generally do not form bonds).
Noble gases have completely filled electronic configuration and hence they are chemically inactive / inert / do not form bond with other elements.
Noble gases, such as helium, neon, and argon, do not typically form compounds because they have a stable electron configuration with a full outer shell of electrons, making them very unlikely to gain or lose electrons to form bonds with other elements.
All noble gases have completely filled orbitals and are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons or form compounds at room temperature.
Noble gases 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 generally donot form compounds under normal conditions.
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.
The Inert Gases of Group 0 rarely combine with other elements as they are (exc. Radon) extremely unreactive. The Inert Gases are:HeliumNeonArgonKryptonXenon(Radon)
