Introducing Nitrogen - The chemistry of almost everything (4/31)

Uploaded by OUlearn on 03.09.2009

It's most of the air we breathe, folks.
But try getting nitrogen to perform.
Come on, you lazy little element, we won't hurt you.
The little creature would prefer to be left alone
to be just part of the atmosphere.
But don't start thinking nitrogen is too lazy to do anything.
It's a good friend to us.
One of the key elements that makes up proteins and DNA,
essential for life.
And it's in most of the fertiliser we add to plants
in the form of ammonium or nitrate.
Some plants use bacteria to convert nitrogen into nitrate.
It also gets converted in the atmosphere by lightning.
Oh, sorry, we forgot to tell you about that bit.
