Dmitri mendeleev was passionate about chemistry. The periodic table of elements was designed independently about the same time by two different scientists. Mendeleev's two preliminary periodic tables.
Mendeleev's periodic table was further refined in 1871. Mendeleev was the first chemist who gave us a proper tabular periodic table. The structure of the table shows periodic trends. With this strategy, mendeleev could organize and rearrange material until patterns emerged. Essential understanding a periodic table shows much information about an element in an element's square, and arranges elements by their electron configuration.
