This is an incomplete question, here is a complete question.
The given molecule is, [tex]SO_3[/tex] and structure is shown below.
Determine the number of shared and unshared electrons in the structure.
Shared (bonding) electrons :
Unshared (lone, non-bonding) electrons :
Answer :
Shared (bonding) electrons : 8
Unshared (lone, non-bonding) electrons : 16
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is, [tex]SO_3[/tex]
As we know that sulfur and oxygen has '6' valence electrons.
Therefore, the total number of valence electrons in [tex]SO_3[/tex] = 6 + 3(6) = 24
Bonding electrons : These are those electrons that are shared between the atoms resulting in the formation of bond.
Non-bonding electrons : They are the valence electrons of the atom which are not shared with another atom.
According to Lewis-dot structure, there are 8 number of bonding electrons and 16 number of non-bonding electrons.
