The Lewis structure for the chlorite ion ClO2- (Cl atom, 2 oxygen atoms, and one negative charge)

Seems like Cl is the central atom and two oxygen atoms are both connected to it. Oxygens only have 6 outer electrons, but in the lewis structure on the book, seems like one of the oxygen atom does not have any electrons contributed to covalent bonding? You can find it on page 80 (topic 2B).

When would it be the case that one or more of the atoms just don't contribute any electrons to the covalent bonding in a molecule?

When I do Lewis structures, what works for me is not looking at what each atom is contributing, but rather looking at the total amount of valence electrons as a whole. Yes, you are right in thinking that Oxygen usually has two bonds and that results in the oxygen having a formal charge of 0. However, the formal charge is not always 0 and that can be seen when Oxygen has one bond.
