For the last fifty or so years, the periodic table has been incomplete. Elements after uranium on the periodic table have been synthesized for the past few decades, but there were always a few ...

A breakthrough in heavy-element chemistry shatters long-held assumptions about transuranium elements. Researchers have ...

“The discovery provides new understanding of how berkelium and other actinides behave relative to their peers in the periodic ...

The discovery of radioactivity in 1896 by Henri Becquerel from a uranium sample, and subsequent research by Enrico Fermi and others from 1934 on, eventually showed that 235 U can undergo a chain ...

Unlike other elements reportedly gathered by Lidden, the plutonium sparked a major hazmat alert, requiring a response from the Australian Border Force (ABF) officials, firefighters, and police. He and ...

The zigzag, staircase, line in the diagram of the periodic table above separates the metals, on the left, from non-metals, on the right. Hydrogen is a non-metal, but it is often put in the middle.

The researchers named the molecule berkelocene because its structure is analogous to a uranium organometallic complex called “uranocene ... Traditional understanding of the periodic table suggests ...

Four have filled gaps in the periodic table of 92 elements and five have extended it beyond uranium By I. Perlman & G. T. Seaborg Join Our Community of Science Lovers!

One of the proud achievements of Oak Ridge National Laboratory is the discovery of three elements either by its own staff or in collaboration with other institutions in the United States and Russia.

Scientists have discovered “berkelocene,” the first organometallic molecule to be characterized containing the heavy element berkelium. The breakthrough disrupts long-held theories about the chemistry ...
