That means it can hold more than eight valence electrons. Although they are few, some stable compounds have an odd number of electrons in their valence shells. BrF3 molecular geometry is said to be T-shaped or trigonal bipyramidal (as discussed) with a bond angle of 86.2°, which is slightly smaller than the usual 90°. Each fluorine atoms has nine electrons, and there are seven valence electrons in the outer shell of the Bromine molecule, out of which three electrons form bonds with three fluorine atoms. People also ask, is BrF3 trigonal planar? As you can see, the remaining 4 valence electrons are placed on bromine as lone pairs. Brf3 Polarity, Molecular geometry, Hybridization, and Bond angle, It forms a T-shaped molecular structure and has Bromine. Hence its hybridization is sp3d. The electron pairs in multiple bonds are treated collectively as a single super pair. Science.
