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

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 ...

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 ...

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 ...

Elements heavier than uranium don’t exist naturally on Earth. Researchers make these massive elements at the end of the periodic table by smashing existing atoms together in particle accelerators.

Whether you are an aspiring Chemistry student or just a normal know-it-all geek, the Periodic Table offers you the simplest way to keep tabs on the atomic elements and their chemical properties. And ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

Two weeks ago, we showed off our favorite entries in C&EN’s “I Spy a Periodic Table” photo contest. And we gave readers a chance to pick a favorite of their own in an online poll. It was a tight race, ...
