Elementymology

If you have a nose for names, you'll love this fantastic site put together by Peter van der Krogt. It's an astonishingly well-chronicled and well-detailed library for researching names of chemical elements. I swear it's not a waste of time. There's loads of trivia to be devoured. More importantly, from a lingusitic angle, you can pick a smattering of Greek, Latin, Sanskrit and Russian, on the way.
