Autoethnography As time passes one sees the changes that occurs within themselves such as interest and skills. Reflecting on my past made me realize that as a kid I have always loved to play soccer but the problem was that I wasn't the child prodigy like most of the kids were.
Dmitri Mendeleev was a Russian chemist who lived from 1834-1907. He is considered to be the most important contributor to the development of the periodic table. His version of the periodic table organized elements into rows according to their atomic mass, and into columns based on chemical and physical properties.Using his table, Mendeleev was able to predict characteristics of undiscovered elements.To unlock this lesson you must be a Study.com Member.hile constructing his version of the periodic table, Mendeleev noticed that some spaces were better left empty, because there was no known element that had the necessary characteristics. Mendeleev hypothesized that these empty spaces were for elements that had not been discovered yet.
Prominent Russians: Dmitry Mendeleev. February 8, 1834 â February 2, 1907. Mostly known in the West for creating the Periodic Table of Elements, Dmitry Mendeleevâs contribution to the development of Russia is huge.A real Renaissance man, his areas of study ranged from chemistry to aeronautics to Arctic exploration to demographics.endeleevâs greatest contribution to science is certainly the Periodic Table of Elements, which says the properties of basic elements repeat periodically when they are arranged by their atomic number. He made the discovery in 1869 during his work on the award-winning textbook on chemistry basics.
