I'm not sure whether this may have appeared here before, but I recently discovered yet another brilliant BBC Documentary (on Youtube) …
BBC Documentary: Chemistry A Volatile History.
(Just follow the subsequent links for each episode).
I highly recommend this one .. its one of the best I've seen so far, and traces the history of Chemistry, starting with its ancient origins in Alchemy, to the discovery of the elements, and all the way through to modern times.
Its presented by Jim Al-Khalili (my favourite science presenter).
It was nominated for the 2010 British Academy Television Awards in the category: Specialist Factual.
Somewhat unfortunately, the uploaded Youtubes don't cover the entire series, however most episodes are there.
For anyone wanting to acquire some condensed background on Chemistry and the various intersections with Nuclear Physics at a general fairly basic level, its absolutely fantastic !
(I'm kind of excited about this discovery).
Cheers
