To expand it further, the oxygen atoms in sulphate ion acts as ligands (arms) and it will have a tendency to attract the metal to form a bridge or connection. The sulphate ion, SO 4 2-The sulphate ion is bonded like this: The negative charges are found on two of the oxygen atoms. When you see sulfate, the first thing you … For example, let’s take a neutral metal PtSO4 wherein the sulfate ion acts as a bidentate ligand. Put lone pairs on atoms. It is a salt of sulfuric acid. Now all of the electrons are accounted for and 2 of the oxygen atoms are electro-negative. Here we draw a bond between the unpaired electrons. This connection of a chemical compound bonding with metal is called a chelate. Let’s re-draw what we have illustrated here. The sulfur atom is happy with valence shell complete and its formal charge is neutral. We begin drawing the Lewis dot structure by drawing the 6 valence electrons around each sulfur and oxygen atom.
