Which noble gas element from following exhibits highest number of different oxidation states?

  • Correct answer
    A
    $\mathrm{Xe}$
  • B
    $\mathrm{Kr}$
  • C
    $\mathrm{Ar}$
  • D
    $\mathrm{Ne}$

Solution

Xenon has large atomic size and lower ionisation enthalpy compared to $\mathrm{He}, \mathrm{Ne}, \mathrm{Ar}$ and $\mathrm{Kr}$. Hence, xenon exhibits highest number of different oxidation states.

Hence, the correct answer is option: 'A'.
