All noble gases molecules are _______? (1) Monoatomic (2) Diatomic

Answer: Monoataomic

The noble gases, also recognized as inert gases and aerogens, are the elements of the modern periodic table in group 18. The following are the members that are identified as Nobel gases.

  1. Helium (He)
  2. Neon (Ne)
  3. Argon (Ar)
  4. Krypton (Kr)
  5. Xenon (Xe)
  6. Radon (Rn)

The outermost shell of the Nobel gases are completely filled, so they are inert in nature having general formula of electronic configuration ns2 np6.

The combination of two terms mono and atomic implies a single atom is monatomic. The noble gases are monatomic gases as they are unreactive in nature that is a property of these gases.
