1 Dimitri Mendeleev was probably the greatest scientist produced by Russia. ... 2 the periodic table was developed by Mendeleev, as well as five other scientists, over a period of about 10 years, after the Italian chemist Cannizzaro had published a consistent set of atomic weights in 1860.he elements tellurium and iodine occurred in the wrong order on the basis of their atomic weight Mendeleev's 1869 Periodic Table. 1  Mendeleev noticed that there were regular repeating patterns and similarities between different elements when they were ordered in terms of their atomic weights.
