 Cluster chemistry

Chemistry of finite bonded groups of atoms with molecular or metal-like skeletal bonding. Localized bond counts, skeletal-electron rules and delocalized shell models apply in different regimes.

Cluster chemistry is a branch of chemistry that focuses on the study of clusters, which are small aggregates of atoms or molecules, typically ranging from a few to a few hundred atoms. These clusters can be composed of metal, non-metal, or semiconductor elements and can exhibit unique properties that differ significantly from those of individual atoms or bulk materials.
