-Not sure why this is wrong other than the comma. Maybe someone else will elaborate.

- wrong because "them" & "which" together is wrong. But if "which" is deleted then sentence becomes a run-on sentence. To correct problem we must delete "them". Then "which" is acting as a relative pronoun for subatomic particles.

Wrong: This model explains all known subatomic particles, SOME OF WHICH only recently discovered.
- Wrong because verb missing after "some of which"

This usage (of which some were) looks perfectly fine. I doubt anyone will be able to find an error here.
