Determine the number of shared and unshared electrons in the structure.
Total number of shared electrons: 8
*For each bond, or line drawn, it counts as two electrons. Thus, since there are four total bonds, there are eight shared electrons.
Total number of unshared electrons: 16
*Unshared electrons are represented by dots in lewis dot structures. So we can simply count each dot to arrive at 16 unshared electrons.
Determine the number of shared and unshared pairs of electrons in the structure.
Total number of shared pairs of electrons: 4
*Each bond, or line drawn, represents a shared pair of electrons. Thus, since there are four total bonds, there are four shared pairs of electrons.
Total number of unshared pairs of electrons: 8
*Unshared electrons are represented by dots in lewis dot structures. So we can simply count how many pairs of dots there are, which represent lone pairs. In this case, there are 8 total lone pairs.
Determine the total number of valence electrons in the structure.
Total valence electrons: 24 (6 from sulfur and 6 from each oxygen)
*Both oxygen and sulfur fall under the same group of the periodic table (16), which have 6 valence electrons each. So we can simply do 6 x 4 = 24 valance electrons.
