In the Periodic Table application you can find a large amount of data about chemical elements for free. You will learn a lot of new and useful for yourself, no matter you are a schoolboy, student, engineer, housewife or an individual of any other provisions that does not have a refresher to Chemistry.

The chemistry falls into to number of the most important sciences and is one of the main school objects.

Its studying begins with the Periodic Table. Interactive approach to a training material is more effective than classical. As in it technologies which became the family for the modern pupils are used.

The periodic system of chemical elements (Mendeleev's periodic table) is a classification of chemical elements that establishes the dependence of various properties of elements on the charge of the atomic nucleus. The system is a graphic representation of the periodic law established by the Russian chemist Dmitri Mendeleev in 1869. Its initial version was developed by Dmitri Mendeleev in 1869-1871 and established that the properties of elements depended on their atomic mass.
