Tabel Periodik Unsur Kimia -

Periodic Table of Chemical Elements Complete with an explanation of each element

Dear buddy count, this is the application of a complete chemical chemical table. This application is in the form of a complete periodic table. To use it is very easy to tiggal tabs on the elements you want to see, a complete popup will appear about these elements. Starting from the atomic number, the distribution of electron leather, the name of the element, group, the element group, the atomic weight, the configuration, the valence electron, the atomic radius, the radius of the ion, the ionization energy, the boiling point, the melting point, the history of the discovery of the elements, the year of the discovery, the source of the element and the usefulness and benefits. Super complete anyway. The application of Tabel Periodik Unsur Kimia is very easy to use to help you learn at home. For example, the boron element tab friend in the periodic table application of the element will appear data:
