Tables charting the chemical elements have been around since the 19th century – but this modern version has a short video about each one.

In the short time since launching this site, our videos have been watched more than 1.8 million times.

But we’re not finished yet. We’ve started updating all the videos with new stories, better samples and bigger experiments.

So once you’ve watched all 118 videos, make sure you come back and check on our progress. We still have a few surprises up our sleeves!

The video above is a short introduction. Find out more at periodicvideos.com

Excellent resource; thanks Ewan.
