Determine the charge on the sulphur atom in the lewis structure of the SO4^-2
Accepted Answer
The Lewis structure of SO4^-2 is O=S(=O)-O^-. The sulfur atom is bonded to four oxygen atoms. Three of these bonds are double bonds, and one is a single bond. The sulfur atom has six valence electrons, and each oxygen atom has six valence electrons. The double bonds contribute four electrons each, and the single bond contributes two electrons. This gives the sulfur atom a total of 26 valence electrons. The sulfur atom has a formal charge of +2.
