As of 2019, the Periodic Table of the Elements has been around for 150 years. Maybe you've felt a certain chemistry with 2019 but don't know why? Maybe it's because this year marks the 150th ...

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 ...

A MODERN table of chemical elements must show electronic configurations as well as the variation in the properties of the elements with atomic number. It should also include the lanthanide and ...

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 ...

THE “periodic” classification of the elements plays such an important part in courses of inorganic chemistry for students that a large wall diagram illustrating this classification has now become a ...

In a significant breakthrough for the scientific community, a new element has been confirmed on the periodic table. This discovery holds potential implications for a wide range of scientific fields, ...

On a stage in the United Nations Educational, Scientific, and Cultural Organization headquarters in Paris, Yuri Oganessian holds a microphone in one hand and a small remote control in the other. Over ...

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 ...

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 ...
