Question

What are noble gases? Give examples.

Answer 1

Noble gases

• The noble gases, also known as the inert gases and the aerogens, are the elements that belong to group 18 of the modern periodic table.
• Under standard conditions for temperature and pressure, all the noble gases exist in the gaseous phase.
• 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 mono atomic gases.

The elements that belong to this group are:

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