Today's Google doodle celebrats Dmitri Mendeleev's Birthday.
Highlights
- Dimitri Mendeleev formulated the first Periodic Table in 1869
- The Periodic Table lists the atomic structure of all known elements
- Element called Mendelevium with atomic number 101 was named after him
During our schools days all of us have studied the Periodic table of elements. But do we really know the man behind it?
Google today celebrats the 182nd birthday of Russian chemist and inventor Dmitri Ivanovich Mendeleev with a doodle. He was the one who formulated the periodic law, which lead to the organisation of the 63 elements known as periodic table. Dmitri developed his extended version of the periodic table.
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.
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.
