This is an incomplete question, here is a complete question.
The given molecule is, 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,
As we know that sulfur and oxygen has '6' valence electrons.
Therefore, the total number of valence electrons in = 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.
