(D) The $Xe$ atom has $8$ valence electrons in its outermost shell.In $XeF_2$,$2$ electrons are used for bonding with $F$ atoms,leaving $6$ electrons which form $3$ lone pairs.In $XeF_4$,$4$ electrons are used for bonding,leaving $4$ electrons which form $2$ lone pairs.In $XeF_6$,$6$ electrons are used for bonding,leaving $2$ electrons which form $1$ lone pair.Therefore,the number of lone pairs in $XeF_2$,$XeF_4$,and $XeF_6$ are $3, 2, 1$ respectively.

What are the number of lone pairs of electrons on the central atom in $XeF_2$,$XeF_4$,and $XeF_6$ respectively?
