Question

Give reason:

Noble gases are chemically inert.

Answer 1

Nobel gases: The noble gases are the elements that belong to group 18 of the modern periodic table. The elements that belong to this group are:

• Helium (He)
• Neon (Ne)
• Argon (Ar)
• Krypton (Kr)
• Xenon (Xe)
• Radon (Rn)

Noble gases, also known as inert gases as they are known to possess extremely low chemical reactivity (hence the name inert gas). This is because all the noble gases have stable electronic configurations. This is the reason why noble gases do not form molecules easily and are mostly found as monoatomic gases.
