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. Einfach, weil diese Apps ein verrücktes verdammt einfaches Design enthält, gut aussehend und leicht zu verständlich zu sein, weil alle Elemente in verschiedenen Farben gruppiert sind. This Best Periodic Table is also very easy to use. Wenn Sie die Details eines Chemie -Elements wissen möchten, müssen Sie es einfach Tabelle und sehr vollständige Daten dieses Elements in einem Dinamyc -Pop -up erscheint. Just scroll down on it to know more about that element. Viele Informationen beginnen aus dem Überblick, der Atomnummer, der Shells, des Elementnamens, der Gruppe, der Klassenelemente, der Atomgewichte, der Konfigurationen, der Valenzelektronen, des Atomradius, der ionischen Radius, der Ionisierungsenergie, des Siedepunkts, des Schmelzpunktes, der Geschichte der Entdeckung des Elements, der Entdeckung, der Quelle dieser Elemente sowie der Nutzen. This is a sample data of an element in this Best Periodic Table .
