Question
Assign reasons for the following:
Of the noble gases only xenon is known to form well-established chemical compounds.
Solution
Xenon is larger in size hence bigger the size force of attraction decrease over the electron thus Xenon is known to form well established chemical compounds also (a) the first ionisation energy of xenon gas (1170 KJ mol–1) is fairly close to that of oxygen (1166 KJ mol–1).
