Is there any fundamental difference between ionic, covalent, and others types of bond? A canonical perspective on the question.

摘要: The concept of chemical bonding is normally presented and simplified through two models: the covalent bond ionic bond. Expansion ideal models leads chemists to concepts electronegativity polarizability, thus classification polar non-polar bonds. In addition, intermolecular interactions are viewed as physical phenomena without direct correlation in any simplistic model. Contrary these traditional bonding, recently developed canonical approaches demonstrate a unified perspective on nature binding pairwise interatomic interactions. This new model, which force-based approach with basis fundamental molecular quantum mechanics, confirms much earlier assertions that fact there no distinctions among bonds, including hydrogen bond, halogen van der Waals
