The chemical bond is defined, and students learn to distinguish between ionic and covalent Introduction to Bonding: The chemical bond is defined, and students learn to distinguish between ionic, ...

Chemical bonding enables scientists to take the 100-plus elements of the periodic table and combine them in myriad ways to form chemical compounds and materials. The success rate is pretty good, as ...

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 ...

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 ...

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 ...

For the first time, scientists have engineered an enzyme that can break stubborn man-made bonds between silicon and carbon that exist in widely-used chemicals known as siloxanes, or silicones. The ...

Anna Azvolinsky reports work on artificial photosynthesis (15 April, p 28). She writes that plants “store their energy… in chemical bonds. In other words they make fuel”. This risks reinforcing the ...

Figure 1 BNOSE, a high-performance, chemically recoverable elastomer design based on boron-nitrogen (B-N) coordination and boron-oxygen (B-O) dynamic bonding. Elastomers, or thermoplastics, are ...
