Group 18 - Noble Gases

Xenon forms compounds because:
Select the correct option:
Solution
Incorrect! Answer:
All of these
For a long time, Noble gases were called 'inert'. However, Xenon (Xe) can form stable compounds (like XeF2,XeF4) for several reasons:
- Ionization Energy: Xe has the lowest I.E. among noble gases (comparable to Oxygen), allowing it to lose/share electrons with highly electronegative atoms (F or O).
- Atomic Size: Large size means valence electrons are less tightly held by the nucleus.
- d-Orbitals: The availability of empty 5d orbitals allows Xenon to promote its electrons and expand its octet to accommodate more than 8 valence electrons.
