New Delhi: Tech giant Google wishes Dmitri Mendeleev a happy 182nd birthday by redesigning their logo to honour the iconic Russian chemist. If you're still wondering who Dmitri Mendeleev is?
Dmitri was the man who formulated the Periodic table of chemical elements.He not only placed the elements in their correct positions in the table, accounting for existing errors in valency and atomic weights, but also predicted correctly, leaving spaces for elements that were then undiscovered.
He latter predicted the properties of seven of these missing elements and their compounds.
Mendeleev's table, published in 1869, correctly organised the 63 known elements based on their atomic mass.
Dmitri Ivanovich Mendeleev was born on 8 February, 1834 at Verkhnie Aremzyani, in the Russian province of Siberia. In 1869, he published the Mendeleev's table, the first recognized periodic table which consisted of all the 63 known elements (at the time) which were arranged based on their atomic mass.
He also accurately predicted elements that were yet to be discovered, leaving spaces in the Periodic table, three of these elements were discovered in his lifetime which led to the table being widely acknowledged in the scientific community.
Mendeleev made other important contributions to chemistry. He made important contributions to the determination of the nature of such indefinite compounds as solutions.
After him was also named mendelevium, which is a synthetic chemical element with the symbol Md (formerly Mv) and the atomic number 101. It is a metallic radioactive transuranic element in the actinide series, usually synthesized by bombarding einsteinium with alpha particles.
