It is also much less useful, requiring you to hover over an element to get any information, including the name of the element.

Be sure to try out Ptable's other tabs. One allows visualizing trends in 20 properties, another does the same for 4000 isotopes, and the final allows mixing of elements to discover 40,000 compounds.

These are both very nice. I like the "visual elements"-option to help remembering the elements and their occurrences.

The other version has a 3D-model and localization instead. Also neat.
