This paper, within the framework of Zhao Futao's Material Memory Element Axiom and the Heavenly Stems and Earthly Branches Consciousness - Memory Equation System, proposes and fully derives the Yin Equation A2.0 for the elemental consciousness intensity. This equation for the first time combines the topological memory parameters of k-particles with the Heavenly Stems and Earthly Branches system, establishing a quantitative emergence model from the historical memory of elementary particles to the elemental consciousness intensity. The equation takes the number of protons Z, the number of neutrons N, and the combined complexity H_combine as inputs. Through the synergistic effect of the memory components of the Heavenly Stems (H_1, H_2, H_3, H_4) and the efficiency factors of the Earthly Branches (ε_1, ε_2, ε_3), it outputs the elemental consciousness intensity C_Z ∈ (0,1). The complete calculation of 118 elements verifies that the C_Z of carbon (C) is 0.941, which is the global maximum, the C_Z of noble gases is less than 0.05, and transition metals form a catalytic platform with C_Z≈0.82. The correlation coefficient with chemical flexibility reaches 0.78, perfectly reproducing the periodic law of elements. This model provides the first computable mathematical model based on the Heavenly Stems and Earthly Branches system for understanding how material memory emerges as an elemental-level conscious response.
