Since element 99 -- einsteinium -- was discovered in 1952 from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is ...

On the periodic table, most elements have at least one stable form. But others have only unstable forms, all of which decay by emitting radiation and transforming into different elements until ...

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 ...

Theo Gray collects elements and has put together this awesome Periodic Table Table. This week Reactions explores the science and chemistry going on inside this periodic table. Step into his office, ...

The periodic table of chemical elements hangs in front of chemistry classrooms worldwide and is an icon for science. Yet much was unknown about its history -- until now. The periodic table reflects ...

Last week, we explored the evolution of the periodic table, with all its elements in order. Now that we’re well-organized, let’s dive into the reasoning. * The table is generally sorted by the number ...

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 ...

“To develop the scientific temper, humanism and the spirit of inquiry and reform.” These words were crafted in 1976 in an amendment to India’s constitution. The constitution’s writers rightly saw the ...
