I'm trying to understand why ChemReference sometimes lists the valence electrons as a number I don't expect. Take Oxygenoxygen, for instance. It should have six valence electrons, however the site lists two. Why?

I hear that, for transition metals, the d-orbitals count towards the valence. Is there another rule like that I need to know about that might explain Oxygen?
