Fractality of Abundance-weighted N,Z-Chart of Isotopes and Systematics of Atomic Weights of Chemical Elements

Sa？etak We show that stable isotopes display a fractal pattern in the N,Z-chart and abundance-weighted chart of isotopes with the fractal dimension df ≈ 1.2. On this basis a scale invariant power law for atomic and molecular weights can be introduced and applied to systematics of Chemical elements and compounds
