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 ...

The periodic table has been a vital foundational tool for material research since it was first created 150 years ago. Now, researchers add an entirely new dimension to the table, offering a new set of ...

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 ...

The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could successfully predict their masses, densities, how they would link up with other ...

PARIS, January 29. /TASS/. Russian scientists will hold the first experiments at the Super-Heavy Element Factory in Dubna near Moscow in April to synthesize the 114th and 115th elements of Mendeleev’s ...

At the middle of the 19th century, 63 chemical elements were known to science. Before Mendeleev’s discovery, attempts at arranging them in some logical way were made by Johann Doebereiner (1829), ...

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 ...
