It helps to figure out the number of bonding and a non-bonding group of electrons. \\ SO_3 \\ 1. The two carbon atoms form a sigma bond in the molecule by overlapping two sp 2 orbitals. Therefore the uniform charge distribution occurs and no polarization occurs across the XeF4 molecule. {eq}\rm XeF_4{/eq}, xenon tetrafluoride, has a total of 36 valence electrons (8 from Xe and 28 from 4F). Therefore, XeF4 molecular geometry is square planar. Step 8: Therefore, the net formal charge on the XeOF4 molecule is zero indicating that the above derived Lewis structure is most accurate for this molecule. Dots are used to characterize the electrons and lines are drawn to show the bonds between two atoms. This means that Al is more electronegative than H. So AlH3 is a polar molecule, not a nonpolar. In the best possible Lewis structure for a molecule, the octet of all or most atoms is satisfied and the individual formal charge for each atom is equal to or close to zero. This also helps us understand the combining capacity of various elements and why do they atoms form chemical bonds. For CF3Cl: How many bonding pairs?
