Question

Fluorine forms chemical compounds with:

• A. Helium
• B. Neon
• C. Argon
• D. Xenon

Answer 1

The correct option is D Xenon

The $Xe$ has total of $8$ outside shell $e^{-}$

While the Florine has $7$ valence electrons.

$X{e}^{\prime }s$ outside shell electrons are very far away from the center, therefore $Xe$ can't pay attention to all of the electrons. Florine is smaller, therefore it has stronger positive attraction to the four electrons it has left.

'F' is only element that react with $Xe$ because it is most electronegative. It is the only element that is strong enough to pull electrons out of the stable Xenon
