If you could explain it that would be great too. So now if you put 6 electrons around each F. Now you should have something like this http://www.chemprofessor.com/bonding_files/image01... Now count up the electrons in the structure and you'll see that there's 6 on each F atom(symbolized by dots) and 2 between the F atoms(symbolized by a dash/line) so that's a total of 6+6+2=14 so since there's 14 electrons in the structure you've accounted for all 14 valence electrons so you're done. Two, 4, 6, 8; that Fluorine has 8. Etiquetas lewis-structure, molecular-structure. Lewis dots are very confusing to me. Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDS), are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. First start with a bonds between the two F's, so start with F-F. Now the octet rule says each atom must have 8 electrons distributed around it so right now each atom only has 2 electrons(the line/dash/bond represents 2 electrons and yes the 2 electrons belong to both of the F atoms so that's why each F has 2 electrons). 6.- La forma de las moléculas.
