From what I can tell I do have a listener badge for "Introduction to the atom" which is a subtopic of "Atoms, molecules, and ions" which is a subtopic of "Chemistry".

I don't have a listener badge for Chemistry as a whole though. So this seems to suggest that here too, only the 6-video sub-sub-topic is actually counted as a 'topic' for badges.
