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 ...

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 ...

The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom ...

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), ...

This year marks the 150th anniversary of the Periodic Table, and the principles that drove Dmitri Mendeleev to construct his table are still influencing today's research advances. This year marks the ...

A new chart for highly charged ions (HCIs) has been proposed, aiming to replicate the conventional periodic table’s ...

The periodic table merges scientific inquiry, international politics, hero worship, desires for structure and desires for credit. Formally, the modern periodic table is a systematic arrangement of the ...

First established in 1869, the periodic table quickly took the scientific world by storm as a means of properly organizing elements. Beyond being a helpful learning tool, the periodic table allowed ...

GALLIUM IS an unusual element. It is a light, silvery metal, similar to aluminium. But unlike aluminium, if you hit it with a hammer it shatters like glass. It melts at about 30°C—in your hand, or ...

Russian chemist may have peeked at predecessor's work, but he still should get credit for modern chemistry, says author. Michael Kanellos is editor at large at CNET News.com, where he covers hardware, ...

Kelling Donald receives funding from The National Science Foundation, and the Dreyfus Foundation. The periodic table merges scientific inquiry, international politics, hero worship, desires for ...
