Uranium forms an unusually strong triple covalent bond with nitrile groups, confounding predictions about the bond strength of actinides compared with the remainder of the periodic table. Elements ...

The molecule features both radical-based dynamic covalent bonds and coordinate bonds. News organizations may use or redistribute this image, with proper attribution, as part of news coverage of this ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...

An international research team led by Dr. Florian Auras from Dresden University of Technology (TUD) has succeeded in developing a new type of material in the rather young research field of covalent ...

For a little more than a century, chemists have believed that strong atomic links called covalent bonds are formed when atoms share one or more electron pairs. Now, researchers have made the first ...
