Elementium

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.

更新履歴
Pinch to zooooom! Elementium now supports one of the most natural gestures you use every day on your iPhone or iPad: two finger pinch-to-zoom.

PINCH TO ZOOM
Use two fingers to zoom in or out on the Periodic Table. Double tap to reset your zoom level. Note that I have removed the on-screen zoom in / out buttons. However, the new zoom behavior supports both keyboard shortcuts (“Cmd” + “+” and “Cmd” + “-“) and accessibility zoom actions.

As part of this update I’ve also entirely rewritten the Periodic Table layout engine. This means the table should now be more responsive to different screen sizes and accessibility settings. It should also be quite a bit smoother!

As always, stay tuned for more new features and content soon — I have a lot of big updates coming shortly! And, if you like Elementium, please take a moment to leave a review on the App Store.
