According to Lewis theory, the total number of

σ

bond-pairs and lone pair of electrons around the central atom of

XeO_{6}^{4 -}

ion is ______ .

Answer: 6

XeO X_{6} X^{4 -}

the central xenon forms six

σ

bonds to the six oxygen atoms. The number of electron domains around xenon is six with no lone pair, giving an octahedral arrangement. The total of

σ

bond pairs and lone pairs around xenon is

6 + 0 = 6
