Dmitri Mendeleev [SEP] Introduction
Dmitri Ivanovich Mendeleev (often romanized as Mendeleyev or Mendeleef) ( ; , , ; 8 February 18342 February 1907 ) was a Russian chemist and inventor. He is best remembered for formulating the Periodic Law and creating a farsighted version of the periodic table of elements. He used the Periodic Law not only to correct the then-accepted properties of some known elements, such as the valence and atomic weight of uranium, but also to predict the properties of eight elements that were yet to be discovered.
