Webb4 aug. 2024 · In Lewis Structure, we show the bonds in the structure by drawing a straight line between two atoms. So all these bonds will take up 12 valence electrons out of 48. Place all the remaining valence electrons around the Fluorine atoms and check if the octets of all the fluorine atoms are complete.
