Water has many anomalous physical and chemical properties that result from its molecular structure (Table 1). The polar nature of the molecule helps to explain its high dielectric constant and its ...

Researchers at Ruhr University Bochum, Germany, have shed light on the structure of supercritical water. In this state, which exists at extreme temperatures and pressures, water has the properties ...

Researchers have recorded the first observations of the molecular structure of liquid water at a gold electrode under different battery charging conditions.

Water is made of molecules. Each water molecule is made from two hydrogen atoms chemically bonded to one oxygen atom. This means that the chemical formula of water is H₂O.

In this publication, published on May 18, 2025, in the Journal of American Chemical Society, Prof. Rickhaus and his team focus on molecules called carpyridines, shaped like microscopic saddle. Just ...

The molecule is held together by chemical bonds that create a slightly negative charge on the oxygen atom and a small positive charge on each of the hydrogen atoms. This unequal charge distribution ...

Hydrogen tunnels: water molecules trapped within beryl channels. (Courtesy: Alexander Kolesnikov et al./Physical Review Letters) Water molecules trapped in tiny channels exist in a blurry quantum ...

When a water molecule is trapped, quantum tunneling lets its hydrogens spread out and make a new shape.

There are a number of distinct ways that the molecular components of water can line up into a solid, which is why the compound’s phase diagram is so strange.

In this diagram of methane (CH₄) the chemical bond between atoms is shown as a stick. One molecule of the compound methane is made from one carbon atom and four hydrogen atoms.
