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.

What’s New

Version 1.6.0

I have been overwhelmed at the recent support for Elementium -- thank you to each and every one of you. This update, as requested, includes localizations for Spanish, French, German, Dutch, and Portuguese. There are also a few improvements behind the scenes to get Elementium ready for future updates, new features, and bug fixes. Yay!

Localizing an app is difficult. Localizing an app that has specific, critical terminology can be very difficult. I have done my best to provide accurate localizations for the following languages. If you notice an issue in your language, please send feedback using the "Give Feedback" button in the "Guide" so that it can be corrected quickly.
• Spanish
• French
• German
• Dutch
• Portuguese

Tap on a Bohr model to view it in full screen, in all of its beauty. Tap again to dismiss.

Quick access to the Periodic Table from your device's Today View (even on the Lock Screen). To add the new Periodic Table widget to the Today View, open the Today View, scroll to the bottom, tap EDIT, then add "Periodic Table" to your widgets. Hurrah! Elements even closer to your fingertips now.

Small, behind-the-scenes bug fixes. Hopefully you didn't notice them to begin with (but if you did, hey, check out that "Apply to Beta Test" button). Those of you who experienced a crash with Study Mode, it should now be fixed. However, it is proving slightly elusive. If there are still issues after this update, expect a fix in the next day.

Again, thank you for all your support. Share Elementium with your classmates and teachers -- it is my hope that this becomes a useful tool for everyone.

“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!

whatever it takes!!! ,

Nice layout in iPad; crashes on 6G iPod Touch

Easy and intuitive to use, I like the variation in colors to show the differing elements. There’s plenty to learn about each element within the app as well as links to Wikipedia to learn more. I first downloaded this app to my 6G iPod Touch where it always crashed. The iPad version is stable. Both of my devices are running on iOS 12.2.
