The Sulfur Dioxide i beg your pardon is likewise known together Sulphur Dioxide is the entity of a bond between Sulfur and also Oxygen atoms. That is well-known as a formula written as SO2. Here we will carry out an explanation the SO2 molecular geometry, SO2 electron geometry, SO2 shortcut angle, and also SO2 Lewis structure.

You are watching: What is the total number of outer (valence) electrons in sulfur dioxide, so2?

We understand that the shape which minimizes the repulsions of electronics pairs is embraced by the molecule to type the structure. The molecular form of SO2 is very same as the molecule geometry of Carbon Dioxide (CO2). Us will show the bonding the SO2 without making presumption below.

O === S === O

Now, if we want to inspect the precise molecular shape of SO2, then us should recognize the location and number of electrons distributed in between Sulphur and Oxygen. In the external level, Sulphur has actually six electrons, and the Oxygen has four of them among which one electron is supplied for each bond. Therefore total variety of ten electrons in five pairs. To make bonds, four pairs room needed, therefore one pair remains alone. The two dual bonds use two pairs every and form as a solitary unit. 

As the solitary alone pair no counted in the shape’s description, we deserve to conclude that the molecular form of SO2 is V-Shaped or Bent. So, our first perception that the initial structure does not enhance with the original one. 


Difference that Electron Geometry Vs molecule Geometry

Though there are so countless similarities in between the electron geometry and also molecular geometry, there room some an essential differences. Among the most notable differences is the the electron geometry can be connected with one or more molecular shapes. It relies on the main atom’s structure of electron of the molecule, when the molecule geometry relies on the various other atoms also which are bonded come the central atom or the totally free pairs of electrons.

SO2 Electron Geometry

The electron geometry that SO2 is created in the shape of a trigonal planner. The three pairs the bonding electrons i ordered it in the plane at the angle of 120-degree. Together the one pair remained alone, two double pairs space bonded and form a bend shape.

SO2 Lewis structure

To create the Lewis structure of SO2, you must arrange the eight valence electron on the Sulphur. To design the best Lewis structure, you also need to calculate the formal fee of every atom too. You know that both the Sulphur and also Oxygen has actually six valence electrons each. Below we have actually two Oxygen atoms, therefore a total variety of valence electrons will certainly be eighteen.

We will ar Sulphur in ~ the center and Oxygens at outsides. Now we will placed the pair of electrons between the atoms to create bonds.Now let’s calculate the formal charges.For Oxygen:No. That valence electrons = 6No of bonds = 2Lone pairs = 2So, Formal charge (FC) = No. That valence electron – No. Of bond – 2 X (No. That lone pairs) = 6-2-(2×2) = 0For Sulphur:No. The valance electron = 6No. Of binding = 2Lone pairs = 2So, FC = 6-2-(2×2) = 0Now, we will kind the structure by perfect the octet with the many electronegative aspect O. Us will ar a dual bond and a single lone pair v each atom that Oxygen.We will finish the framework by placing the remained valence electrons on the main atom. Right here we have 4 bond pairs and also four lone pairs, so complete electrons provided are (4+4) x 2 = 16. So, the variety of remained valence electrons room 18-16 = 2. We will placed these electron on the atom the Sulphur.So, our last Lewis framework of SO2 will be like:


SO2 shortcut Angle

The SO2 has a bond angle of 120-degree. One single atom the Sulphur is bonded with two atom of Oxygen covalently. It causes a repulsion that electron pairs to type the 120-degree angle.

Is SO2 Polar or Non-Polar?

By analyzing the Lewis structure of SO2, we have the right to see the the SO2 is asymmetrical since it contains a region with different sharing. The molecule geometry that SO2 has a bent form which means the top has less electronegativity, and also the bottom inserted atoms the Oxygen have much more of it. So, the conclusion is, SO2 is a Polar molecule.


Here, us have described the molecular geometry, electron geometry, Lewis structure, bond angle, and polarity the SO2 (Sulfur Dioxide).
