The iconic chart of elements has served chemistry well for 150 years. But it’s not the only option out there, and scientists are pushing its limits. By Siobhan Roberts When Sir Martyn Poliakoff, a ...

Last week, we explored the evolution of the periodic table, with all its elements in order. Now that we’re well-organized, let’s dive into the reasoning. * The table is generally sorted by the number ...

Discover the significance of rare-earth elements, their applications in technology, and the global race for their resources.

The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance ...

The periodic table stares down from the walls of just about every chemistry lab. The credit for its creation generally goes to Dimitri Mendeleev, a Russian chemist who in 1869 wrote out the known ...

Do you have a favorite chemical element? Neurologist Oliver Sacks did—he was partial to dense, high melting-point metals, especially those metals between hafnium and platinum on the periodic table.

It’s another raw day in St. Petersburg, Russia, but the man striding down the University Embankment along the Neva River isn’t pondering how the icy wind off the Gulf of Finland chills his bones or ...

But the periodic table didn’t actually start with Mendeleev. Many had tinkered with arranging the elements. Decades before, chemist John Dalton tried to create a table as well as some rather ...

This lesson utilizes an adaptation of the board game Periodic: A Game of the Elements to help students better understand both general periodic trends and the law of conservation of energy. This ...

A team of Russian and American scientists announced today the creation of several atoms of the previously unknown element 117. The discovery of “ununseptium” will eventually fill a longtime gap on the ...

“LA république n’a pas besoin de savants ni de chimistes.” With that curt dismissal a court in revolutionary France cut short the life of Antoine-Laurent de Lavoisier, argued by some to be the ...
