# What is the number of valence electrons for SBr_4?

And so we got $S B {r}_{4}$, i.e. ${6}_{\text{sulfur"+4xx7_"bromine"=34*"valence electrons}}$...17 electrons pairs to distribute by VESPER... Electronic geometry around sulfur is thus $\text{trigonal bipyramidal}$ to a first approx. and molecular geometry is conformationally mobile $\text{see-saw}$. The ""^19F $\text{NMR spectrum}$ of the homologue $S {F}_{4}$ would SHOW the one signal given the soft, easy exchange of equatorial and axial halides....
