The Best Periodic Table Application for Your Android Mobile
Hi guys, this is my fourth application, Easy Periodic Tabel. It's one of Best Periodic Table apps for your android. Just 3 words, simple, easy, and complete. Simple because this apps contains a crazy damn simple design, good looking and easy to uderstand because all elements grouped in different colors. This Best Periodic Table is also very easy to use. If you want to know the details of a chemistry element you just have to tab it and a very complete data of that element will be appear in a dinamyc pop up. Just scroll down on it to know more about that element. A lot of information start from the overview, the atomic number, shells, the element name, group, class elements, atomic weights, configurations, valence electrons, atomic radius, ionic radius, ionization energy, boiling point, melting point elements, the history of the discovery of the element, years of discovery, the source of these elements as well as the usability and benefits. This is a sample data of an element in this Best Periodic Table.
