Lewis Dot Structure of the sulfite ion SO3-2 – Electron Dot Structure

Lewis Dot Structure of the sulfite ion SO3-2

simple method for writing Lewis Structures is given in a previous article entitled “Lewis Structures and the Octet Rule.Several worked examples relevant to this procedure were given in previous posts please see the Sitemap – Table of Contents (Lewis Electron Dot Structures).
Let us consider the case of the sulfite ion. The chemical formula is SO3-2 . 
What is the SO3-2 Lewis structure?

Draw Lewis structures of SO3-2 step by step:

Draw Lewis structures
The Lewis structures of Nitrogen Monoxide NO are drawn.
2.Total valence electron is 6+3×6 -(-2)= 26
Connect the atoms of the sulfite ion (SO3-2) with single bonds.
3.Connect the atoms with single bonds.
4.P=6n+2 -V =6×4 +2 -26 = 26-26 = 0 ; 0 electron which must be shared through pi bonding and unshared i.e; Therefore, there is 0 double bond and an electron..
5.Distribution of other electron
6. Complete the octet shells   : Electrons are placed around each atom so that the octet rule is obeyed. Since S is a third row element can accommodate more than 8 valence electrons.
7. Calculare the formal charege….

The lone electron is placed on the S atom which is more electropositive than O and can accommodate better a positive charge
