It dovetails nicely with one of the many free resources from absorblearning – in this case an animation of an oxygen atom bonding (covalently) with two hydrogen atoms to form a water molecule.

There are over 100 other free resources like this from the same site (you can see more on the right-hand side of the pages).
It would be ideal if one could link directly to the resourse but instead you have to click on the icon on the top left to arrive at the required distination. Just as well it’s worth the trip.
The plan is put links to most of these in the relevant junior chemistry page of thephysicsteacher.ie

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.
