In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary particles ...

In a unique experiment, researchers have clocked how long it takes for an electron to be emitted from an atom. The result is .00000000000000002 seconds, or 20 billionths of a billionth of a second.

For the first time, scientists visualized how electrons behave during a chemical reaction, which could help reduce unwanted byproducts in future chemistry.

You may be familiar with matryoshka dolls: nested sets of painted figurines that fit within painted figurines. In the case of wooden dolls, the concept is pretty straightforward: hollow out a large ...
