The article introduces a theory of spherical metal cluster, which considers electric dipole quantum transition of valence electrons by means of effective polarizability. It is shown that effective polarizability of the valence electrons of spherical metal cluster possesses negative dispersion in a broad wave band from 450 to 1000 nm, that leads to negative extinction of a metal sphere.
