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 ...

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 ...

Naturally occurring superheavy elements beyond those listed in the periodic table could potentially explain why asteroid 33 Polyhymnia is so dense, new research suggests. When you purchase through ...

Four new elements joined the periodic table in 2016. These superheavy elements only exist for seconds at a time before they decay, making it hard for scientists to pin down their properties.

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), ...
