HW 2F.3

for 2F.3 a), why does SO2 have two sigma bonds but only one pi-bond? I thought there are two pi-bonds

I think that's because the textbook used the resonance structure where there is one single-bonded O and one double-bonded O, and so as a result there is only one pi bond.

But the formal charges would not be zero...
