Chemical bonding “is the heart of chemistry,” according to Alexander I. Boldyrev, a chemistry professor at Utah State University who spends his time thinking about how molecules are put together. “But ...

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 ...

Because bond order is a chemical concept, and not an observable in the quantum mechanical sense, there does not exist a unique definition of bond multiplicity in quantum chemistry. Thus, it is ...

The carbon-hydrogen bond -- 2/3 of all bonds in hydrocarbons -- has defied chemists' attempts to open it up and add new chemical groups. A team has now cracked the strongest of C-H bonds, those on a ...

Sharing more leads to tighter bonds – even in the world of molecules. The most detailed images yet made of the chemical bonds in a molecule vividly show what large-scale models had long assumed: ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the ...

Using advanced microscopy techniques, researchers have recorded the breaking of a single chemical bond between a carbon atom and an iron atom on different molecules. The team used a high-resolution ...

What makes diamond the hardest substance in the world and graphite—the stuff of pencil lead—comparatively so soft? Both are made of nothing but carbon atoms. The answer lies in the chemical bonds ...
