Elements on the BBC

I try not to focus my posts too much on other websites – it seems as if it is a bit of a cheat but over the last few months the BBC magazine (found on the BBC website) has been producing some excellent articles on various elements in the periodic table – you may have read some yourself.

 

However, what has not been so widely publicised it the fact that the written articles have accompanying downloadable podcasts of around 30 minutes – and the quality is excellent!

In this post you will be able to find a link to the pod casts and a small summary on the accompanying BBC magazine article and a link to it.

Podcasts:

Here is a link to the 23 podcasts that the BBC has commissioned:

You will see that Silicon, Sulfur, Tungsten, Vanadium, Nitrogen, Carbon, Chlorine, Lithium, The Rare Earths, Calcium, Tin, Gold, Mercury, Aluminium, Helium and Phosphorous have all been included.

Below is a link to the associated BBC magazine article and a short summary of it:

Vanadium: The metal that may soon be powering your neighbourhood:

The power may come from a Redox Flow Battery – that is very similar to cyclic phosphorylation (that you may have covered in Biology)

Nitrogen: The Bringer of Life and Death

Ammonia and explosives, as well as a pseudo inert gas – that’s Nitogen for you!

Don’t forget that it is also used in mood stabilising drugs!

Helium: Is it Right to Waste Helium on Party Balloons?

And why would a gushing oil geyser initially not catch fire?

No more explanation needed!
