Dmitri Mendeleyev was born in Tobolsk, Russia, on February 8, 1834. was a chemist and inventor. Mendeleyev is best known for his discovery of the periodic law and for his formulation of the periodic table of elements. He died in St. Petersburg, Russia, on February 2, 1907.
As he began to teach inorganic chemistry, Mendeleev could not find a textbook that met his needs, so he set out to write one " The Principles of Chemistry, but the work most famous was the creation of the periodic table that is still used today. It was when he wrote his book that he discovered similarities in the progression of atomic weights, and wondered if other groups of elements exhibit similar properties.
what impresses me about him was that when presenting the periodic table he left empty boxes for elements that had not yet been discovered but he had foreseen his atomic weigth and properties. time after this was demonstrated by the chemical Lars Fredrik Nilson when he discovered a element that completed the empty boxes.
It takes a great organization to make a complete table!
ReplyDeleteHe was a genius. He thought the table leaving empty boxes!!!
