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 1.7.0

This update comes with much needed bug fixes, some new content, and a few feature updates.

Fixes an issue where searching for an element would display random results across the periodic table.

Updated element card layout to include links to ScienceDirect's encyclopedic content for each element.

Drag down to dismiss an element card.

Better Siri integration. Setup a shortcut to have Siri show the Periodic Table, as well as suggest it on the Lock Screen or Spotlight when appropriate.

Elementium is now 90% written in Swift. This means faster and more frequent updates for you -- with fewer bugs. Woohoo!

“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!

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.

Whoever made this app must be a super hunk and super smart; because it’s great and the person behind the computer I just know is great, too. Ooops I love him, what do I do? I miss you.
