The Best 55 Online Periodic Tables

Best Periodic Tables Online
Since its beginning, Triple Point has a category devoted to Periodic Tables where I write about the best periodic tables on the Internet. The idea of building a ranking like this begun before the hiatus this blog has suffered. I started collecting URLs of some interesting periodic tables and found myself with a huge list of addresses. My plan was to present a top 10 or a top 20 so I started cutting. My selection was based on factors like content, design, originality and usefulness. At the end I’ve got a list of not 10, neither 20 but 55 great online periodic tables!
I’ve selected periodic tables written only in English or Portuguese, so I intentionally left out many periodic tables written in Spanish, German, Chinese or Japanese, for instance. However many ranked periodic tables have versions in several languages.
This is not a final choice. This post will stay permanently open and I expect to update it very often with more high quality periodic tables. More, I would like to hear your suggestions. If you use or know periodic tables that you think should integrate this ranking write to me or leave a comment. Thanks.
So, let’s go to the ranking of the best periodic tables:

My Other Science Blog: Science Quick Picks

Science Quick Picks is a typical cut-and-paste blog, which I maintain as a sort of bookmarks collection of interesting science news and resources and share with my readers. Science Quick Picks has now around one thousand posts and some of them are quite popular. On the restart of Triple Point I leave here links to some of the most recent and to some of the most popular posts:

The transfer is finally complete! I had more problems than I had expected, but this blog is now ready to function in WordPress. I have yet minor things to do like checking links but the primary task is complete. The site’s structure is almost the same. The main modification is that the best chemistry sites now have their own page named The List. In this list you can find the sites I consider to be the most valuable chemistry resources. All these sites were previously reviewed in Ponto Triplo (my Portuguese blog). You can find some of these reviews translated to English in this blog.
I hope to restart posting shortly. In the meantime, if you detect some errors please let me know. Thanks.


More than one year after the last post, this blog will rebirth in a new home. Triple Point will move from TypePad to WordPress in the next few days. Expect some turbulence. I will post again after setting everything up.
