This free app on the Periodic Table of Elements has such a sleek design and is so informative that you would be very hard pressed to find a paid app which offered a similar product.
The table is presented in vivid color that makes it easy to follow and understand the grouping of each chemical element.
EMD PTE provides the full periodic table of the elements. Each element can be selected and a panel appears which gives the element's name, how it got that name, the chemical properties of the element and a blurb on the person who discovered it, and when.
The app also features a search engine to locate any element in an instant. The table itself can be manipulated to show images of the discoverers and a time line to see the history of how the table progressed and was discovered. You can also adjust the table to see the atomic properties of each element.
A “state of aggregation” slide bar manipulates the table and you can at a glance see how temperatures affect the state of each chemical (i.e. when each becomes a liquid, gas or solid).
The app also offers a mass calculator. Enter in a chemical formula and it will show the result of the reaction including percentages of chemical elements present after the reaction takes place.
Another great property is that each element is shown visually with a microscopic photo of how it looks.
This app is the ultimate tool for any student of chemistry. It offers a ton of functionality and information and is 100% cost-free and ad-free.
Compatible with iPhone, iPod touch, and iPad.
