Descripción:
In 1862, French geologist named Alexandre Beguyer de Chancourtois published a list of all the known elements. Although flawed as it contained some ions and compounds, and also was put into geological terms without a diagram. Leading to it being ultimately ignored until Mendeleev reworked it.
