So4 -2 Lewis Structure

To draw any Lewis structure, you must first count the available valence electrons. Group 16, has 6 valence electrons. Oxygen (O): Group 16, has 6 valence electrons each (

At this stage, every atom satisfies the . However, this is not the most stable version of the structure. 4. Calculate Formal Charges so4 -2 lewis structure

In the basic octet-only version, Sulfur has a formal charge of and each Oxygen has -1 . Because Sulfur is in Period 3, it can expand its octet to reduce these charges. To draw any Lewis structure, you must first

While the structure calculated in Section 3.3 shows two double bonds, resonance theory dictates that the double bond character is evenly distributed. There are six equivalent resonance structures where the double bonds rotate among the four oxygen atoms. However, this is not the most stable version
