Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.

From the above structures, there are two extra electrons over the two oxygen atoms of SO3 and SO4 entities while in case of SO2, octet is completed with no extra electrons. Hence, SO32- and SO42- form divalent ions.
