To determine the shape of a molecule, VSEPR theory is used. Bromine (Br) is the central atom in BrF₅, having 7 valence electrons. Five Fluorine (F) atoms are bonded to Br, each forming a single bond. This accounts for 5 valence electrons from Br being used in bonding, forming 5 bond pairs. The remaining 7 - 5 = 2 valence electrons form one lone pair on the central Br atom.
Which one of the following is the shape of BrF₅?
