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.

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®.

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.

A built in solubility calculator* answers all your, "is this soluble in that", questions. Just specify a solvent and a solute to check their compatibility. A solubility lookup table is also available for cross-referencing multiple combinations.

See beautiful depictions of elements from raw to processed, and in other forms. The extensive library of images help you understand what your lab samples should look like, or may be helpful to students learning about chemistry.*

Search for elements by name, symbol, mass, or number from within Elementium™ or via Spotlight. 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 visualize how electrons are oriented around the nucleus.*

Academics and students writing reports and using data frequently in the classroom or the lab can simply tap on an aspect of an element to export its information.*

Add the Periodic Table widget to your home screen for quick and easy reference to the Periodic Table. Or, try out the "random element" widget which is useful for students.

• Custom app icons
• Set temperature and atomic radius to your preferred units
• Search Spotlight for elements
• Thoughtfully developed with accessibility in mind
• A subscription is totally optional
• No account required
• Privacy focused (no tracking, no data collection)

What’s New

Version 3.4.3

Hi there! This update to Elementium includes a few bug fixes and improvements.

Many of you have been asking for the ability to change units of measure without the need for a subscription. You can now do this. Units of measure are now included as part of the one-time purchase for "Advanced Tools". Of course, if you're an ION subscriber, you'll still get all the same great benefits.

Those of you who use Elementium on iPad with iPadOS 15 or iPadOS 16 will also notice a number of small improvements and fixes for some cosmetic bugs.

As always, stay tuned for more new features and content soon! And, if you like Elementium, please take a moment to leave a review on the App Store.

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.

Great app.

I am a layperson with only high school education. I get curious sometimes and turn to Elementium to satisfy that. So much of this content is over my head. But the in app links to Wikipedia is pretty cool. It has definitely paid off while yelling out responses at the TV during Jeopardy!

Sawdust & Noise ,

Was Five Stars, Then ...

After the latest update, the app began throwing ads. That's instant deletion as far as I'm concerned. It's gone.

Update: What comes up when the app starts for the first time is an ad for an in-app purchase. It takes over the screen in an irritating fashion, and it is not obvious how to get rid of it. There does not seem to be any further aggravation, but time will tell.

Other than that, it's a great app.

Developer Response ,

Elementium has no ads. It never has. It never will. That's a promise.

This is an education app and resource for students, teachers, professionals, and enthusiasts alike. One of my highest priorities is providing a safe, privacy-focused, and positive learning experience for everyone. That's why there aren't any ads at all. Ever.

I'm so sorry you had a negative experience and I'd love to hear more about it from you. Please send me an email at hello[at]samspencer.art. I hope to hear from you, and hope you'll give Elementium another chance!
