Lewis notation

Lewis notation - exercises

Lewis model: Representation of the bonding and free electron pairs, observing the octet rule.
                         
Lewis notation: electrons (e-) are marked as a point and e - pairs are marked as a dash.

             
Example: chlorine molecule

binding electron pair

 

Lewis notation:

Give the Lewis formula for carbon dioxide (CO 2 ) at.

 

 

There are atoms that can attract the bonding pair of electrons more strongly. Due to the uneven distribution in the molecule, they receive a partial negative charge. The strength increases in the following row:
