The user interface is focused on a single chemical element at a time. The whole periodic table is a secondary UI component, giving you "the big picture" without distracting from what's important.
Chemical elements that are liquid or gas at rest are animated, and each state change (e.g., from solid to liquid) is animated as well.
You can influence the element state by changing its temperature, in a dedicated panel. A slider lets you control the temperature, displayed according to the Celsius, Fahrenheit, or Kelvin scale.
The periodic table can be navigated in multiple ways. You can swipe from one element to another, you can touch the element map, you can scroll the element list, or you can even search for an element name in the search panel.
You can bookmark any chemical element you like. Bookmarked elements will appear in a special map, in a dedicated panel.
You can also take notes for any chemical element you like. Notes will appear in a dedicate panel, besides the name of the element. You can even export your notes, via email or on your clipboard for easy copy & paste in other apps.
A single tap on the element symbol brings you to the Properties section. We stored as much information as we could in there. Element properties are grouped in categories: Basic, Electromagnetic, Thermodynamic, Nuclear, Material, and Atomic.
In the basic group you have displayed the electronic configuration and an image (if available). A single tap and the image will zoom out in all its glory.
For many properties, you can convert the temperature scale (Celsius, Fahrenheit, and Kelvin) or the energy unit of measure (eV or kJ/Mol).
Furthermore you can copy single properties or the entire list in the clipboard, or export it via email. You can do the same with the picture of the element.
If in doubts, you can search what each property means on Wikipedia or you can look at the element properties on Wikipedia or Wolfram Alpha. All right from inside the app.
