Original Old Periodic Table

He did so by writing the properties of the elements on pieces of card and arranging and rearranging them until he realised that by putting them in order of increasing atomic weight certain types of element regularly occurred. Brand tried to discover the philosophers stone a mythical object that was supposed to turn inexpensive base metals into gold. Russian chemist dmitri mendeleev published the first recognizable periodic table in 1869 developed mainly to illustrate periodic trends of the then known elements.

Its creation is a perfect illustration of how science progresses. The history of the periodic table is also a history of the discovery of the chemical elements. He also predicted some properties of unidentified elements that were expected to fill gaps within the table.
