The size, or the number of atoms, the material, or the type of the atom(s), and the charge, or the oxidation state, are the central parameters that define the properties of atomic clusters, or, more generally, finite systems. The different isomeric forms of clusters, as well as their electronic, optical, magnetic, and other features are all defined by these three parameters. For a chosen material, however, it is ultimately the size that plays the decisive role. Afterall, the sensitivity of the different features to the charge is itself a finite-size effect.
