So it will be in the central position with both these Fluorine atoms on the terminal ends.įluorine atoms need one valence electron to complete its octet so it will share one valence electron of the Sulphur atom. And now that we know the total valence electrons of SF2, we will start making the Lewis Dot Structure for this molecule.įirstly, place the Sulphur atom in the centre as it is less electronegative than Fluorine. Lewis Structure is the pictorial representation of the arrangement of valence electrons around the individual atoms in the molecule. So, Sulphur Difluoride has a total of 20 valence electrons. Total number of valence electrons for SF2 – 6 + 7*2 ( as there are two atoms of Fluorine, we will multiply the number by 2) Sulfur has six valence electrons in its outer shell. Total number of valence electrons for SF2 – Valence electrons of Sulphur + Valence electrons of Fluorine

So we will first find out the total valence electrons for Sulphur Difluoride. You are watching: Identify the molecular geometry of sf2įor drawing the Lewis structure for any molecule, we first need to know the total number of valence electrons.

In this blog post, we will look at the Lewis dot structure of SF2, its molecular geometry and shape. It has a chemical formula of SF2 and can be generated by the reaction of Sulphur Dioxide and Potassium Fluoride or Mercury Fluoride. Sulfur Difluoride is an inorganic molecule made up of one Sulphur atom and two Fluorine atoms.
