Which of the following noble gases forms interstitial compounds with metals?

$A$ xenon compound '$A$' upon partial hydrolysis gives $XeO_{2}F_{2}$. The number of lone pairs of electrons present in compound $A$ is ....... . (Round off to the nearest integer)

Given below are two statements:
Statement-$I$: Noble gases have very high boiling points.
Statement-$II$: Noble gases are monoatomic gases. They are held together by strong dispersion forces. Because of this,they are liquefied at very low temperatures. Hence,they have very high boiling points.
In the light of the above statements,choose the correct answer from the options given below:

The inert gases are

$XeF_6$ on partial hydrolysis gives '$X$' and $HF$. The shape of '$X$' is

Which of the following statements is $NOT$ true for noble gases?
