  1. DMITRI MENDELEEV BY: Rachel FOWLES Period 8

  2. Personal Background • Mendeleev was born February 8th 1834 in Tobolsk, Siberia • He was the youngest of 17 children born to Ivan Pavlovich and Maria Dmitrievna Mendeleev • By age14 he showed promise in science • When he was 17 he went to study natural science at St. Petersburg, where he graduated in chemistry in 1856 • He married FeozvaNikitchnaLascheva in 1863 and then divorced her and married Anna IvanovaPopova in 1882 and had 6 children between the two of them • He became a Professor of Chemistry first at the Technological Institute of St. Petersburg and then in 1866 at the University • He died on February 2nd , 1907

  3. SUMMARY OF RESEARCH • His research ranged from questions in applied chemistry to problems of chemical and physical theory • His research dealt mainly with Agricultural Chemistry, Oil Refining and Mineral Recovery • In 1870, Mendeleev stated that it was possible to predict the properties of undiscovered elements • He researched and made predictions for three new elements (eka-aluminum, eka-boron and eka-silicon) and suggested several properties of each

  4. CONTRIBUTIONS/ DISCOVERIES • Mendeleev’s most famous achievement and MAIN contribution was his organization of the elements into a periodic table that could be used to predict their properties • When making the Periodic Table Mendeleev began by arranging the elements in order of increasing atomic mass and placing elements with similar properties next to each other • He realized that he might have to leave gaps in the table as not all the elements had been discovered • He published well over 250 writings in his lifetime, on science and also on his beliefs

  5. EXPERIMENTS • Mendeleev experimented with studies on the properties and behavior of gases at high and low pressures which led to his development of a differential barometer and further studies in meteorology • In 1887 Mendeleev attempted to observe a solar eclipse from a hot air balloon, this was quite a risk because he did not know how to control or land the balloon

  6. Discovery's EFFECT ON THE ATOM • Mendeleev was the one who helped organize everything that came before him and his organization of the Periodic Table led to predictions of new elements that weren't discovered yet! • Mendeleev’s work effected everything that came after him because though the Periodic Table is organized differently today, his organization led to new ideas for organization of the table This is an example of what Mendeleev’s Periodic Table (from 1871) looked like
