A simple procedure for writing Lewis Dot Structures was given in a
previous article entitled
“Lewis Structures and the Octet Rule”.
Step 1:
Connect the atoms with single bonds
Step 2: Calculate the # of electrons in π bonds (multiple bonds) using formula (1):
Therefore, there are 3 possible Lewis resonance structures for
NO_{3}^{}
The above simple fourstep method for drawing Lewis structures is presented in the following video:
Lewis dot structures NO3 ion  nitrate ion  method to draw dot structure on line textbook, Lewis structure of no3 with formal charges, lewis structure of no3 molecule, resonance structures of no3, resonance structures of no31, resonance lewis structure of no3, lewis dot structures of no3
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 nitrate ion.
The molecular formula is NO_{3}^{}.
Fig. 1 : Connect the atoms of NO_{3}^{} with single bonds 
Step 2: Calculate the # of electrons in π bonds (multiple bonds) using formula (1):
Where n in this case is 4. Where V = (5 +6*3) – (1) = 24
, V is the number of valence electrons of the nitrate ion.
Therefore, P = 6n + 2 – V = 6 * 4 + 2 – 24
= 2 So, there is 1 double
bond.
Step 3 & 4:
The dot resonance structures
of NO_{3}^{} _{ }areas follows:

Which of the above structures contributes more to the resonance?
ReplyDeleteThe above resonance structures are all equivalent because of the same charge separation and bond order. They are all contribute equally to the resonance.
