Dmitri Ivanovich Mendeleev (often romanized as Mendeleyev or Mendeleef) (English: /ˌmɛndəlˈeɪəf/MEN-dəl-AY-əf; Russian: Дмитрий Иванович Менделеев,[note 1]tr.Dmitriy Ivanovich Mendeleyev, IPA: [ˈdmʲitrʲɪj ɪˈvanəvʲɪtɕ mʲɪnʲdʲɪˈlʲejɪf](listen); 8 February 1834 – 2 February 1907 [OS 27 January 1834 – 20 January 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.
