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 ...

The rare radioactive substance made its way from the United States to Russia on a commercial flight in June 2009. Customs officers balked at accepting the package, which was ensconced in lead ...

If you wanted to create the world’s next undiscovered element, number 119 in the periodic table, here’s a possible recipe. Take a few milligrams of berkelium, a rare radioactive metal that can be made ...

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 ...

As Class 10 Science exams approach, students are revising the periodic table using smart memory techniques rather than rote ...

This illustration shows a typewriter with the keys depicted as the periodic table. Hands are typing on it, and the sheet of paper coming out of it shows the words "Tales from the table." Credit: Chris ...

At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature. In fact, they ...

In chemistry, we have He, Fe and Ca — but what about do, re and mi? Hauntingly beautiful melodies aren’t the first things that come to mind when looking at the periodic table of the elements. However, ...

This year marks the 150th anniversary of the publication of Mendeleev’s Periodic Table of Chemical Elements in 1869. In celebration, the United Nations Educational, Scientific, and Cultural ...

Researchers used a particle accelerator and co-precipitation to study the chemical reactivity of single rutherfordium atoms. Such experiments will continue the advancement of relativistic chemistry ...
