This interactive periodic table can be used to highlight groups and periods, physical states, elements known in a given year, scarcity of resources, and many other interesting things.

The number of protons, neutrons and electrons in an atom can be changed in this interactive activity, which displays the atomic number, mass number and ionic charge. Atoms can also be selected from the periodic table.

By clicking on the animation tab and then clicking 'step through', you can access animations on covalent bonds and ionic bonds.

An online lesson plan, supported by video clips, which includes the effect of smaller particle size on rates of reaction and the flame colours of different compounds.

A video tutorial with accompanying notes to show you how to safely electrolyse a molten ionic compound, demonstrating that it conducts electricity and decomposes.
