In this case there are three possible resonance structures. Refractive index of carbon tetrafluoride CF the nm wavelength range. The initial Lewis structure should be drawn with each noncentral atom connected by single bond although not all atoms have show bonds.

Placing electrons Once the total number of available has been determined must placed into structure [...]
