Periodic table of Internet
For those of you have ever had to use the periodic table, which I have done the study or something … here I leave a periodic table of the internet. I would have liked me use this
The periodiс table of the chemical elements (also Mendeleev’s table, periodic table of the elements or just periodic table) is a tabular display of the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring (“periodic”) trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior.
