Quickly reference any discovered element on the periodic table. Search for and filter out elements based on classification, phase, and orbitals. Dive deeper to get standard, frequently-used, data like mass, electronegativity, radius, and more.

The complete Periodic Table at your fingertips. Information provided for each element includes the following:
• Symbol, name, and number
• Atomic mass (average values suggested by IUPAC)
• Electronegativity (Pauling scale)
• Electron configuration
• Atomic radius (non-bonded, in Ångströms)
• Melting and boiling points (Kelvins)
• Year of discovery
• State at STP
Additionally, each entry is accompanied by a Wikipedia excerpt describing the element and a link for more information. More data will be adding in future updates!

Elements are laid out in a clear and concise manner that adapts to your device and how you use it. A beautiful, color-coded table helps you quickly distinguish which elements are which and their relevant classifications. View the entire table at once with compact view (18 groups across) or scroll through with the traditional view (32 groups across).

Search for elements by name, symbol, mass, or number from within Elementium. Results are shown directly on the periodic table. Need faster access to element information? Search directly from Spotlight on the lock screen or home screen of your device.

Animated Bohr models for each element help you understand how electrons are oriented around the nucleus.

Press on any element to quickly peek at its details. Press on the Elementium home screen icon to instantly search elements or specify how the periodic table should be sorted for viewing.

Add the Periodic Table widget to your device's Today View for even quicker, easier access and reference to the Periodic Table.

Best Chemistry App

This is my first review and I thought it is worth doing it on this Amazing App. First off, this app is so user friendly and my experience with it has been great. Elementium is a must have for any Chemistry Lover. Second, this app actually cites its sources in a visible place so that if you are confused with any material covered in the app, their sources are right there at your disposal. Third of all, This App has no in-app purchases and no premium version or anything like that. Elementium is a 100 percent free app. That is what makes it so lovable. All in all, Elementium is the perfect app and is one of my favorites.

“Periodically” someone makes a nice app

Nice app. You can tell the developer is passionate about what he does. At first there was an annoying bug but that was immediately squashed and once exterminated made the app so much better. If you need or know someone that needs a period table of elements for fun or for school this might be worth your time checking out.

Developer Response ,

Hi FairReviews! Thank you for the compliment. I'm sorry about the review prompt popping up after every element search. This was a bug and has (hopefully) been fixed in the latest update (v1.6). I hope you can enjoy Elementium now, unbothered by requests to review. Should you run into any other issues please feel free to send feedback to me in the app or from the link on the App Store. Thank you!
