This new bond also challenges our fundamental understanding of what exactly constitutes a covalent bond. ‘Roughly speaking, the cause of this bond is the proximity of the atoms due to the rest of the ...

Using an X-ray diffractor to study the sigma bond. Credit: Yusuke Ishigaki Covalent bonds, the very backbone of organic compounds, are formed when two atoms share a pair of electrons. Back in 1931, ...

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 ...

At Hokkaido University in Japan, researchers led by Takuya Shimajiri and Associate Professor Yusuke Ishigaki have made the first-ever observation of a stable, single-electron carbon-carbon covalent ...

Introduce the question students will investigate in this lesson: If atoms have an equal number of protons and electrons, why do atoms bond to other atoms? Why don’t they just stay separate? Begin to ...

Pain relief drugs like aspirin, and penicillin, one of the world’s first antibiotics, are popular examples of covalent drugs. A covalent bond is a permanent bond between two atoms. When chemists make ...

Add a description, image, and links to the coordinate-covalent-bonds topic page so that developers can more easily learn about it.

A particle with higher electronegativity will attract more electrons. The exception is nonpolar covalent bonds, which form when both atoms have approximately equal electronegativity. There are also ...
