Dipoles and Electrostatic Surfaces XeF4 and ClF3 is loaded Xenon Tetrafluoride and Chlorine trifluoride: pin. Favourite answer. ClF3 has a total of 28 valence electrons. The structure that minimizes repulsions is a trigonal bipyramid (Figure 9.6). ClF3 has 5 electron groups around the central Cl atom. Exception 2: If there are very few valence electrons. Notice that this gives a total of five electron pairs. Lewis Structure are very simple to construct and only take a few short steps. Usually noble gases don't react to form compounds, so this is a pretty unique molecule. So you add 7 + 3 = 10...then you divide 10 by two and you get 5...that number is the number of electron areas you have...i hope you know what electron areas are..This is quicker than lewis structure...notice how you have Cl with 3 single bonds...there are 2 lone pairs on the Cl3 atom to make it five areas...Thus you get a T-shaped! and I'm desperately looking for an answer.
