Internet search giant Google has dedicated a Doodle to Russian chemist Dmitri Mendeleev on his 182nd birth anniversary.
The seventh row of the table was completed last month.
Years passed as Mendeleyev slaved over this developing grid system that paired similar elements in sections ranked by their atomic weight and was also a means of being able to predict the discovery of future elements. There were other doodle ideas that did not make it. One of them shows Mendeleev with the element that he named after himself, Mendelevium (atomic number 101).
The periodic table of the elements (now with 118 elements and counting) adorns science classrooms worldwide.
The final artwork for the Google Doodle was created by artist Robinson Wood in an artistic representation of Mendeleev putting in the final building blocks for his table.
Born in the depths of Siberia in Russian Federation in 1834, Mendeleyev apparently always had a keen love of the sciences, which led him to undertake studies in chemistry in Germany and Russian Federation. He went to school in St. Petersburg and graduated in 1856.
Dmitri Mendeleev is most cited as the inventor of the modern periodic table. They were read by Professor Menschutkin because Mendeleev was ill at the time.
Mendeleev died on February 2, 1907, aged 72, at Saint Petersburg, Russia.
