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.
