He predicted the existence and properties of new elements and pointed out accepted atomic weights which were wrong. This organization surpassed the classification attempts of Beguyer de Chancourtois and Newlands and was published a year before the work of Lothar Meyer. In my opinion Dmitri Mendeleev was amazing, without him we would not have our periodic table nor almost any sense of these elements of ours. I also think that without him we would not have a solid vision of chemistry. In conclusion, Dmitri Mendeleev was a man of wonder and patience. He had a brain like no other and the ability to think. Mendeleev was one of the first scientists of modern times, in the sense that he did not depend entirely on his own work but rather corresponded with scientists around the world in order to receive the data they had collected. He then used their data as well as his own data to organize the items based on their properties. Dmitri Mendeleev received the Nobel Prize in Chemistry for his discovery of the periodic
