Example: Consider the Lewis structure for sulfur tetrafluoride (SF 4) which contains 34 valence electrons. SF 4: 6 + 4(7) = 34. There are four covalent bonds in the skeleton structure for SF 4. Because this requires using eight valence electrons to form the covalent bonds that hold the molecule together, there are 26 nonbonding valence electrons.

2 days ago · The Lewis dot structure for CF4 has a total of 32 valence electrons, with 7 electrons around each fluorine atom (7×4 = 28) and 4 electrons around the central carbon atom. Each Fluorine atom shares one electron around the carbon atom and hence all the octets are completed by sharing of electrons (both Fluorine and Carbon). The second component showed the presence of (CF3)2 C structure in an amount no greater than I0 er cent as a C7F isomer. Askew [1 has identified this isomer a 2-CF3C6F13.
