The premiere periodic table app for iPhone, iPad, and Apple TV. Quickly reference any element and all the information you need. Search for elements by on classification, phase, orbital, mass, or number. Dynamic filters help you understand periodic trends, like electronegativity, at a glance. Dive even deeper to get standard, frequently-used data points such as mass, electronegativity, radius, radioactivity, electron configuration, and more.
LEARN
Each element prominently features:
• Symbol, name, and number
• Atomic mass
• Electronegativity
• Electron configuration
• Atomic radius
• Melting and boiling points
• Year of discovery
• State at STP
• Radioactivity
Elements are also accompanied by discussions on its uses, discovery, and more. You can quickly find more information and publications about each element via links to Wikipedia, Science Direct®, and the American Chemical Society®.
EXPLORE
The periodic table is laid out in a clear, concise manner that adapts to the size of your screen. No more squinting at blurry images of the periodic table from web searches. Beautiful color-coding helps you quickly distinguish element classifications, phases at STP, electronegativity, and atomic radius. Trends and filtering help students who are learning chemistry to visualize patterns.

Elementium version 3.4.1
Updated At: 2023-10-15
Changes: Oct 15, 2023
Version 3.4.1
The "Density, Data and Charts" Update
Thanks for using Elementium! This update includes periodic trend charts, improved element data, density measurements, and reduced download size. And, unfortunately, this is the last update that will support iOS 15. If you're still running iOS 15, now is the time to update your device.
This update also fixes a crash some folks were experiencing on iOS 16.
DENSITY & DATA
This update includes a vast swath of improvements to element data. Most notably, elements now have density data. Density information is displayed for each element (where available) in grams per cubic centimeter. ION subscribers can also sort and filter elements by density. Density data is sourced from the National Institutes of Health PubChem database. You'll also notice a number of improvements to other data points including atomic mass, electron configuration, and discovery year.
CHARTS
ION subscribers can visualize the active periodic trend with interactive charts*. Choose from electronegativity, density, or atomic radius and then tap the new chart button at the bottom of the periodic table. These interactive charts make it easy to visualize trends across the elements.
REPORTING INACCURACIES
If you come across incorrect data, you can now report it so it gets fixed in a future update. To report data inaccuracies, tap the "..." button on an element, and then tap "Report Bad Data".
UNIT TOGGLING
ION subscribers can now change temperature and length units directly while viewing an element. Just tap on an element's boiling point, melting point, or radius to cycle through the available units (e.g. to change from Kelvin to Celsius).
SMALL TWEAKS & IMPROVEMENTS
Atomic mass, when shown in the periodic table, now responds dynamically to the size of the table. For example, at its largest size you should see up to 5 decimal places. At the smallest size, where mass is still shown, you'll only see 2 decimal places at most. And, in my ongoing efforts to improve accessibility throughout the app, dark mode colors are more legible.
STORAGE SIZE
The amount of space Elementium takes up on your device should now be around 33% less than the previous version (that's approximately 60 megabytes!). Huzzah for more space and less data use!
As always, thank you so much for your support. Your votes on the roadmap are both encouraging and helpful, and I'll be working on the most popular requests for the next update. If you're enjoying Elementium please take a moment to leave a review -- it really helps :).
Cheers,
Sam

Elementium version 3.3.0
Updated At: 2023-07-27
Changes: Jul 27, 2023
Version 3.3.0
Hello! I'm excited to share "The Fuzzy Roadmap" update with you all. From the in-app settings you'll find two new items: fuzzy search and roadmap.
ROADMAP
You can now view and cast your vote for planned and upcoming features. Open the in-app settings and choose the "Vote on New Features" option. Here you'll find a list of planned and upcoming features. Tap the up-arrow to cast your vote for the the features you'd like to see implemented the most. I can't wait to see what ideas you're excited about; and remember to check back regularly to see the status of any planned updates.
FUZZY SEARCH
I've begun rewriting the element search algorithm from the ground-up using a new "fuzzy" search technique. This means search results for elements will be a lot more forgiving. For example, searching "Neptune" will show "Neptunium" and searching "Bo" will only show "Boron" and "Bohrium" (instead of every element that has the letters "b" and "o"). The results are much more accurate, more forgiving, and just as fast as before. Because this is such a large change to how search works, you'll need to explicitly opt-in to try it out. I'd love to hear what you think and how it works for you!
I have quite a bit more planned for the coming weeks and months; so stay tuned (and check the new roadmap)! :) Let me know what you think by leaving a review or sending an email to me at hello[at]samspencer.art.
Cheers,
Sam
Elementium version 3.2.0
Updated At: 2023-05-06
Changes: May 6, 2023
Version 3.2.0
Hello chemists! This update includes subtle, but exciting, improvements to the look and feel of element detail screens. You'll also notice a number of performance improvements and bug fixes :). Read on to find out more!
ELEMENT DETAIL LAYOUT
Element descriptions are now much, much easier to read. The color of an element only affects the top portion of the screen, so you can read without straining your eyes (on a higher contrast background). Additional improvements and hints have been added to element info items for customers who use VoiceOver. I've also added a sticky header to element detail screens so you always have quick access to additional element sources, and to close out of your current element.
IMPROVED EXPORTING
Exporting element data is now easier than ever. If you've purchased the "Export" feature, or are an ION subscriber, you'll now see a Share button (upwards arrow in a box) on each element detail screen. Tap on the share button to select the pieces of data you'd like to export. A new "Export all data" option also lets you share all information about an element in one tap of a button. And, of course, you can still export data as before by tapping and holding on a data point.
I want to give a big thank you to Alan for taking the time to provide feedback and insight into the export feature!
CUSTOM TYPOGRAPHY (FONTS)
ION subscribers can now customize the font style (serif, sans-serif, rounded), weight (light, medium, regular, bold), and line spacing to make reading about elements just that much nicer. Find the new options in Settings > Typography.
PERFORMANCE IMPROVEMENTS
You may have noticed unusually long wait times to get the Periodic Table loaded in recent updates. We're talking upwards of 2 (TWO!) seconds. That's a long time to wait around for the Periodic Table. Rest assured, this update reduces your wait time to about 30 milliseconds on most modern devices.
SMALLER THINGS TO NOTE
• Home Screen widgets now open to their displayed element
• Filters & sorting should be more responsive
• Fixed a few iPad layout issues
As always, I want to give a big thank you to everyone who uses Elementium! I appreciate all of your reviews and feedback and read it all (and it often makes my day). So if you're enjoying Elementium, please take a moment to leave a review. If you have any feedback, or just want to say hey, send me an email at hello[at]samspencer.art
Elementium version 3.1.1
Updated At: 2023-02-16
Changes: Feb 16, 2023
Version 3.1.1
Hi there! I've been hard at work on a few wonderful improvements to Elementium these past few months. This update focuses on accessibility, performance, and in-app purchases. And, Elementium is now updated for Apple TV - perfect for projection in your classroom, or on a monitor in your lab.
ION TRIALS
Beginning in this update you'll be able to start a free trial of ION before deciding to subscribe. If you're on the fence about whether some of the features and tools included in ION will be helpful to you, starting a free-trial is a risk-free way to finalize your decision. And, as always, if subscriptions just aren't your cup of tea you can purchase individual features for a single, lifetime price.
PERFORMANCE
Performance improvements are hard to qualify, but here's what I think you'll notice:
• Decreased download size
• Faster app launch time
• More reliable Spotlight results
• Reduced battery consumption when viewing Bohr Models
ACCESSIBILITY
If you use VoiceOver or a screen reader, you'll notice that both the Periodic Table and element details are now much easier to navigate. Periodic elements are now a single VoiceOver item instead of disparate items. I am continuing to work on making Elementium more accessible and would love to hear any feedback; especially about what could be improved.
DEEP LINKING
This one is for all the power-users out there. You can now configure links to open specific elements using the elementium://element-name format. For example, to open the Nitrogen page, you'd use elementium://nitrogen. Improved support for Siri and Shortcuts is on the way; this should help out in the mean time, though!
3.1.1 BUG FIXES
Fixes a number of small issues, including:
• Purchasing a subscription should now immediately unlock all app content (no opening / closing required).
• Links to feedback and support are fixed.
• Resolved a crash that may have occurred on devices running iOS 15 when viewing photos for elements.
I appreciate all of your love and support, and have so much more planned for Elementium over the weeks and months to come. If you enjoy the app, or find it helpful in some way, please take a moment to leave a review. And, if you're an educator or school administrator, I'd love to hear from you about how you use Elementium with your curriculum.
With love,
Sam
