The elementary element

It's element time again and this is the big one. Or rather it's the smallest one, but when you're talking elements, you can't get any more fundamental. I have the pleasure - nay, the honour - to present to you... hydrogen.

It's one of the Royal Society of Chemistry's series of podcasts Chemistry in its Element which I have been enjoying contributing to over the last few months.

What can you say about hydrogen? Take a listen, and you'll find out why I just had to label it the king of the elements, where the least is the greatest.
