Multiple atoms combine to form a molecule, and when the number and types of atoms that make up the molecule change, the properties of the molecule also change significantly. One of the fundamentals of ...

Quantum theory in chemistry explains the behavior of atoms and molecules at the smallest scales, which is essential for understanding chemical reactions and properties. It provides the framework for ...

Thanks to the alternating single-double nature of the bonds, electrons in these orbitals end up delocalized; the differences between the bonds become a bit irrelevant, and the molecule is best viewed ...

The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...

A newly isolated three-atom aluminum ring reveals unexpected chemistry that could help replace costly metals used in ...

Scientists have just created a new, strange type of molecule. It’s made of a bunch of atoms bound together in a ring, like many other, simpler molecules. The team, based at IBM Research, engineered ...

The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could successfully predict their masses, densities, how they would link up with other ...

Scientists are looking for ways to make chemical reactions more efficient with the help of catalysts. This would ideally use ...
