Question

Which inert gas liquifies easily

Answer 1

ANSWER:

Radon can be considered to be the easily liquefying noble gas.

EXPLANATION:

• There are 6 noble gases- 'helium', 'neon', 'argon', 'krypton', 'xenon' and 'radon' that occur naturally. All are inert in their activity as their outermost shell has complete set of electrons.
• They have very weak 'VanDer Waal’s force of attraction', which makes them less reactive and even if they form compounds, they exist for a brief period. Their melting and boiling points show a small difference, so most of the noble gases are liquefied easily and some exist in soluble state too.
• In the periodic group as we move down the liquefaction of noble gases increase.  At room temperature, if the air is made cooler xenon liquefies to a liquid from gas.
• Radon is the last of all but it readily dissolves in water to form a clear liquid.
