[填空题]
Two possible oxides of sulfur are sulfur dioxide,$SO_2$, and sulfur trioxide,$SO_3$.

1.1.State the number of electron domains present around the central atom in each sulfur oxide,$SO_2$ and $SO_3$.
1.2.State the molecular geometry of each structure,$SO_2$ has a    shape and $SO_3$ has a    planar shape.
2.Describe and justify the polarity of each structure, $SO_2$ is  ----待选择----polarnon_polar  and $SO_3$ is  ----待选择----polarnon_polar .
3.State,compare with $SO_2$ and $SO_3$ , which structure would have a shorter bond length. ----待选择----$SO_2$" >$SO_2$$SO_3$" >$SO_3$ .
4.State the number of resonance structures for $SO_2$ =   ;AND describe what is meant by “delocalized” electrons.
