Localized plasmons in small metallic and conductive particles are considered on the basis of the classical electrodynamic approach and an approximate approach based on the surface plasmon resonance method. The results based on the quasi-static integral equation for the surface charge density are also presented. Approximate analytical results for resonant frequencies are presented. It is shown that the approximate approach gives good accuracy in the case of small particles with sizes of the order of several nm. Keywords: localized plasmons, surface conductivity, graphene, fullerenes, integral equations.
