नोबल गैस (Noble gases ; inert gases) : found in the periodic table’s Group 18.
They include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
they exhibit very low reactivity under normal conditions.
Noble gases have a stable electronic configuration with a full outer shell of electrons (except for helium, which has only two electrons in its outer shell).
Noble gases have low boiling points means they exist as gases at room temperature and pressure.
In their elemental form, noble gases exist as Monoatomic
helium is used in cryogenics, as a coolant in nuclear reactors, and in gas chromatography.
Neon is used in lighting, such as neon signs,
argon is used in welding and as a shielding gas in incandescent light bulbs, and
xenon is used in specialized lighting, anesthesia, and in certain medical imaging techniques.
