Square Pyramydal Geometry: 1 lone pair and 5 bonding groups
This BrF5, Bromine pentaflouride, molecule is an example of a square pyramidal geometry. The square pyramydal shape has one lone pair and five bonding groups. The angles are 90 degrees between all the molecules and the top molecule. The angles between all the molecules on the side are 90 degrees also. But between opposite molecules the angle is 180 degrees. The Lewis dot structure for BrF5 has 30 valence electrons and when drawn you have five bonding locations and one lone pair.
