Which of the following noble gases exhibits higher oxidation states ?
Options
- ANe
- BAr
- CKr
- DXe
Correct answer
D. Xe
Step-by-step solution
As we move down the group of noble gases, the atomic size increases and the ionization enthalpy decreases. Xenon has a relatively low ionization enthalpy, which allows its valence electrons to be excited to empty d-orbitals. This enables Xenon to form compounds with highly electronegative elements like fluorine and oxygen. Xenon exhibits higher oxidation states such as +2 , +4 , +6 , and +8 in compounds like XeF ₂ , XeF ₄ , XeF ₆ , XeO ₃ , and XeO ₄ . Neon and Argon do not form stable compounds, and Krypton only fo
