Consider the following examples.
The charge on S is +4 and charge on O is -2 hence +4+(2×-2)=0
Hence the charge on SO2 is zero.
The charge on S is +4 and charge on O is -2 hence +4+(3×-2)=-2
Hence the charge on SO3 is -2.
The charge on P is +5 and charge on O is -2 hence +5+(4×-2)=-3
Hence the charge on PO4 is -3.
The charge on N is +5 and charge on O is -2 hence +5+(3×-2)=-1
Hence the charge on NO3 is -1.
