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. SOLUBILITY CALCUALTOR 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. VISUALIZATIONS 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 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. BOHR MODELS Animated Bohr models for each element help visualize how electrons are oriented around the nucleus.* WRITE & REPORT 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.* HOME SCREEN WIDGETS 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.

Explore 118 elements with a periodic table made for everyday chemistry study. Find an element, inspect its properties and see how it compares with the rest of the table. 1. EXPLORE THE TABLE Pinch to zoom, pan across the table or fit the whole table on screen. Filter by category to focus on metals, noble gases, halogens and other element groups. 2. FIND AN ELEMENT Search by name, symbol, atomic number or category. Use localized or English element names. Open a result to explore its details. 3. LOOK CLOSER Browse Overview, Chemistry, Atomic and More sections. View atomic weight, density, melting and boiling points, protons, neutrons, electrons and electron configuration. Tap an element image to enlarge it and pinch to zoom. Move to neighboring elements with the previous and next buttons. 4. COMPARE PROPERTIES Switch between heat maps for atomic weight, electronegativity, atomic radius, melting point and boiling point. In List view, choose a property and sort from low to high or high to low. 5. KEEP LEARNING Look up terms in the A–Z chemistry glossary and browse articles about transition metals. Choose light or dark mode and your preferred color theme. Use the app on iPhone and iPad without creating an account. OFFLINE REFERENCE The bundled element data and reference content work offline. External websites, ads and App Store purchases require an internet connection. LANGUAGE OPTIONS English, German and Spanish (Mexico) interfaces include localized element names, categories and property labels. Some descriptive chemistry text, glossary definitions and articles remain in English and are marked in the app. FREE CONTENT, OPTIONAL PREMIUM The table, element details, comparisons, glossary, articles and themes are available for free. The free version includes ads. Premium removes ads, with weekly, yearly and lifetime options where available. Prices and eligible offers are shown before purchase.

Verdict

The call

The clearest difference is ads: Elementium at none against Periodic Table's shown. Elementium also leads on update cadence (every 3 weeks vs every 3 months) and ratings volume (602 vs 54). On price, rating, review sentiment and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Elementium sells 9 in-app purchases, starting at $1.99 per month and Periodic Table sells 6 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.6 for Elementium against 4.6 for Periodic Table. That said, the two scores are not equally well evidenced: Elementium has 602 ratings behind it against 54, so its average is the more settled of the two. Written reviews split almost evenly too, at 75% and 75% positive.

UpkeepUpdate frequency

Elementium ships an update every 3 weeks, Periodic Table every 3 months. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
