An international team of scientists has shed light on the extreme ends of neutron and proton numbers. Their goal is to investigate the limits of the periodic table of chemical elements. How far can ...

Back in 1869, the great Russian chemist Dmitri Mendeleev noticed periodic trends in the properties of the elements that he was studying. Mendeleev realized that by identifying these trends and ...

Little is known about the heaviest, radioactive elements in Mendeleev's table. But an extremely sensitive technique involving laser light and gas jets makes it possible for the very first time to gain ...

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 ...

Students learn to describe the pattern in atomic number, atomic mass and atomic radius. Trends on the Periodic Table: Students learn to describe the pattern in atomic number, atomic mass, atomic ...

In their momentary life span, atoms of lawrencium, element 103, may have left a lasting impression on the structure of the periodic table. For the first time, researchers have measured a basic ...

For years, physicists have mapped the stability of atomic nuclei with remarkable confidence. The periodic table, with its neat rows and columns, hides a more chaotic reality underneath, where protons ...

Eric Scerri's delightful "The Periodic Table: Its Story and Its Significance" follows the 1969 classic by J. W. Spronsen, "The Periodic System of Chemical Elements," but is a different treatment of ...

The story of the fifteenth element began in Hamburg, in 1669. The unsuccessful glassblower and alchemist Hennig Brandt was trying to find the philosopher’s stone, a mythical substance that could turn ...

The periodic table captures a subtle pattern that runs through the chemical elements, the fundamental building blocks of everything around us: from the aluminium in bike frames to the xenon gas in ...
