Generally all inert gases like , He,Ne,Ar,Kr,Xe are available as monoatomic elements.
Guess the reason.

Noble gases are relatively inert elements. Give reasons.

He,Ne Ar, Kr (decreasing boiling point)

(a) (i) Describle a method for refining nickel. (ii) Why group 18 elements are called inert gases ? Write the general electronic configuration of group 18 elements. (b) (i) Give the uses of helium. (ii) Ni(II) compounds are more stable than Pt(II) compound.Give reason.

The correct order of solubility in water for He,Ne,Ar,Kr,Xe, is

The correct order of solubility in water for He,Ne,Ar,Kr,Xe, is

Give scientific reasons : Inert gases (zero group elements ) are called noble gases.

Why do we use He , Ne , Ar , etc , gases in decorative lamps ?

Arrange following gases according to a' (He, Ar, Ne, Kr) .
