The Informational Atom: A Unified Macroscopic Geometry of the Periodic Table

This manuscript synthesizes recent derivations within the Informational Constraint Framework (ICF) to show that the discrete, phenomenological rules of 20th‑century quantum chemistry—Pauli Exclusion, Hund’s Rule, orbital hybridization, the Aufbau Principle, and the “half‑filled/fully‑filled” subshell heuristics—are observational shadows of a single macroscopic mechanism: the saturation and relaxation of bounded informational capacities. By modeling the atom as a finite 3D informational geometry operating under standard thermodynamic limits, the structure of the periodic table emerges without invoking abstract quantum patches. The paper further demonstrates that the classic Chromium and Copper electron‑configuration anomalies arise naturally from Topological Load Balancing, a geometric strain‑minimization process on the constraint manifold. A computational engine is provided for reproducibility.
