With the 2012 Christmas Lectures exploring the chemistry of the modern world, we asked some of our friends to choose their favourite chemical element.

Each day in December, we'll publish a new video revealing the elements that really excite and inspire people. 

Featuring, amongst others: Brian Cox, Mark Miodownik, Dick & Dom, Helen Czerski, Dara O Briain, Liz Bonnin and this year's Christmas Lecturer, Dr Peter Wothers. Plus, watch out for some surprise guest appearances.

Thank you to everyone who took the time to pick a favourite element. This collection on the Ri Channel was supported by Dow
