Electron-pair bonding is a central chemical paradigm. Here, we show that alongside the two classical covalent and ionic bond families, there exists a class of charge-shift (CS) bonds wherein the ...

Chlorine will gain an electron and form a negative ion. The ionic bond is the force of attraction between the oppositely charged ions - a positively charged metal ion and a negatively charged non ...

Now, a team of researchers from Hokkaido University has isolated a compound in which a single electron is shared between two carbon atoms in a remarkably stable covalent bond, known as a sigma bond.
