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).

See the elements in their raw, processed, and other forms with beautiful images that help you understand what your lab samples should look like or just to illustrate your own understanding.*

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.*

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.*
Supports the beautiful new Dark Mode on iOS 13.

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.

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!

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!
