Compound number one

Some while ago I covered element #1, hydrogen, in a Royal Society of Chemistry podcast. Now it's the turn of the very first compound ever to exist - and a surprising one at that. Helium hydride.

With the latest science news focussed on big bang discoveries it's the ideal time to take a trip to the earliest venture into chemistry. So take a listen by clicking play on the bar at the top of the page - or if that doesn't work for you, pop over to its page on the RSC site.
