Why can some elements have expanded octects? for example, problem 3.57 in the 6th edition asks for lewis structure of a sulfite ion (SO3)2- and in the expanded octet, sulfur has 10 electrons attached to it. why can this happen and when do i know that a compound has an expanded octet?

If an atom is in the 3p block or lower, they have an empty d-orbital which allows them to have an expanded octet.

Anything from group 3 to 7 in the p block, which are the most common type of used elements, have an expanded octet.
