When drawing Lewis structure to be valid, each atom must have a full octet of 8 electrons (except hydrogen, which only has a duet of 2 electrons). The structure with both of the hydrogens and both of the fluorines bonded to the carbon allows all atoms to have the proper number of electrons (if the lone pairs on the fluorine atoms are included). In the structure below, fluorine has six electrons in three lone pairs (not drawn) and the seventh electron participating in a covalent single bond to the Carbon, which allows the Fluorine to have an octet. Likewise, the carbon achieves its octet by sharing bonds with the two F and two H allows. Hope this helps.

Generating the Lewis dot Structure. To generate the Lewis dot structure, you have to follow the given steps: Find the total count of valence electrons to molecules. In this step, add the total count of valence electrons from all the atoms in a bit. Find the required count of electrons needed to make the atoms complete. A step-by-step explanation of how to draw the LiF Lewis Dot Structure.For LiF we have an ionic compound and we need to take that into account when we draw th.

• The dot diagram shows four lone pairs (4×2 = 8 electrons) plus two double bonds (2×4 = 8 electrons) for a total of 16. It also passes the test! Now that you can draw basic Lewis Dot Diagrams and know where all the bonds go, you can do things like figure out the shapes of molecules and label resonance structures.
