Would it surprise you to know that the periodic table, as we know it, isn’t the first table of elements? That even the order of the elements has changed from its original structure? Like many other ...

Credit for the periodic table of the elements generally goes to Dimitri Ivanovich Mendeleev, but a specialist in the history and philosophy of chemistry says the Russian chemist probably peeked at the ...

A century and a half ago, a Russian chemistry professor published a classification of all the known elements, organized by atomic weight. Today, the system that he created for his students — plus some ...

The periodic table of elements, or Mendeleev’s table, was created in 1869 by Russian chemist Dmitri Mendeleev. This table organizes all known chemical elements by their atomic number, or the number of ...

Every field of science has its favorite anniversary. For physics, it’s Newton’s Principia of 1687, the book that introduced the laws of motion and gravity. Biology celebrates Darwin’s On the Origin of ...

Who made the first periodic table? Other scientists had previously identified periodicity of elements, but on March 6, 1869 Dmitri Mendeleev (photo) presented the first periodic table. Mendeleev was a ...

Google is celebrating the 182nd birthday of the Russian chemist, Dmitri Mendeleev, who created the Periodic Table of Elements, which is memorized by students and chemists the world over. The so-called ...

One hundred fifty years after Russian chemist Dmitri Mendeleev published his system for neatly arranging the elements, the periodic table it gave birth to hangs in every chemistry classroom in the ...

At first glance, the system of chemical elements published by Dmitri Mendeleev in 1869 bears little resemblance to the modern periodic table. But by listing elements in columns, and lining up the ...

On 17 February 1869, Russian chemist Dmitri Mendeleev jotted down the symbols for the chemical elements, putting them in order according to their atomic weights and inventing the periodic table. He ...

At the middle of the 19th century, 63 chemical elements were known to science. Before Mendeleev’s discovery, attempts at arranging them in some logical way were made by Johann Doebereiner (1829), ...
