Answers 1
Answer:
Xenon is an inert gas. Its electronic configuration is [Kr]4d105s25p6 . All orbitals that are filled have paired electrons.
Xenon can combine with even number of F atoms to form XeF2 XeF4 and XeF6 .This is because the promotion of 1, 2, or 3 electrons from the 5p filled orbitals to 5d vacant orbitals will give rise to 2,4,6 half-filled orbitals. The structures are as shown:
It cannot combine with an odd number of F –atoms.
Thus, the formation of XeF3 and XeF5 is not possible. answer is 3) XeF3 i hope it's help you
