Periodic is an ad-free and complete reference to the Periodic Table of Elements. It includes useful information such as an element's atomic weight, electron configuration, melting point, boiling point, atomic radius, ionic radius, and discovery year.

Periodic is a useful tool for every student. All 118 elements can be organized and ordered by name, atomic number, chemical series (or group), symbol, and phase. Each element's icon is color-coded by its phase with pristine graphics.

Version 2.1 keeps all of the features of Version 2.0, but makes the program lighter and more efficient. The graphics on both the Periodic Table and the tables of elements load much faster.

Version 2.1 also adds four main features to Periodic. First, units have been added to the elements' information views. Second, the elements' horizontal information views are bigger and easier to read. Third, now when you rotate your device from an individual element's view, Periodic automatically navigates to that element's view in the Periodic Table--or the tables of elements, depending on the orientation of the device. Finally, when viewing an individual element, you can now swipe your finger to the right along the bottom of the view to navigate back to the view of all the elements.

Periodic is an easy-to-use application that provides accurate information provided by the International Union of Pure and Applied Chemistry (IUPAC). Periodic is an essential, mobile reference to the Periodic Table.
