What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen bond? A hydrogen bond is an electrostatic attraction between an atom and the positive ...

Using a technique called high-resolution atomic force microscopy (AFM), researchers in China have visualized the molecular structure of a hydrogen bond. Image: AFM images of 8-hydroxyquinoline on ...

Nobel Laureate Linus Pauling, Ph.D., predicted in 1939 that hydrogen bonding would prove to be more significant in the field of biology than any other type of chemical bond. His prediction has ...

The hydrogen bonds that form water molecules are responsible for the many properties that make water a unique liquid. However, even today scientists don’t fully understand the science behind ...

A hydrogen bond 1 forms between an electronegative atom (the acceptor) and a hydrogen atom covalently bound to another electronegative atom (the donor). Hydrogen bonds are of key importance in ...

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 researchers have developed a method to precisely measure the strength of hydrogen bonds in confined water systems, an advance that could transform our understanding of water's role in biology ...

Hydrogen bonds are at the very core of life as we know it, and now for the first time ever scientists have managed to visualize these transient molecular associations. A team of researchers from ...
