The Great Chicken-and-Egg of Chemistry: Bonding vs. Stability Revisited

Cherif F. Matta ยท 2026

The chemical bond is a central organizing concept in chemistry, yet it is absent from the molecular Hamiltonian and no "bond operator" exists. Bonding is therefore not a primitive physical entity but โ€ฆ
