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 ...

During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

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.

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

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 ...

Valence Electron Examples: Valence electrons play an important role in the field of chemistry, affecting how atoms interact and bond with each other. These outermost electrons are responsible for ...
