The International Union of Pure and Applied Chemistry Joint Working Party has announced the official names and symbols of the chemical elements formerly known as 113, 115, 117 and 118. The proposed ...

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 ...

It happens all over the periodic table. The chemical symbol for lead is Pb. For mercury, Hg. For antimony, Sb. My chemistry teacher in high school cracked up every time she referred to the symbol for ...

This week, we meet the element lawrencium, which has the atomic symbol, Lr, and the chemical number, 103. It was named in honour of nuclear physicist Ernest O. Lawrence, who worked at the University ...

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 year is the International Year of the Periodic Table of Chemical Elements—and today (March 6), the modern version celebrates its 150 th birthday. To find out more about the table and how new ...

When news breaks, you need to understand what actually matters — and what to do about it. At Vox, our mission to help you make sense of the world has never been more vital. But we can’t do it on our ...
