Pronunciation: [pˈɑːtɪkə͡l ɪn ɐ bˈɒks] (IPA) 
The term "particle in a box" refers to a theoretical model in quantum mechanics that describes a particle confined within a fixed space. This model is used to study the behavior of electrons in an atom, and it is also used to explain the properties of other subatomic particles. Other synonyms for "particle in a box" include the "quantum square well" or the "infinite potential well," as the particle's motion is confined within a square-shaped potential with infinite walls. This term is used interchangeably with other models, such as the "harmonic oscillator" or the "hydrogen atom," which are used to describe different systems in quantum mechanics.
