Nuclear Electron Continuous Dynamic Equilibrium Motion Mechanism

The interior of an atom is an extremely high vacuum environment, free of particles and obstacles that can enter the atomic scale. Therefore, extranuclear electrons experience no energy loss through resistance, friction, or collision during motion and can sustain continuous movement solely by their own inertia. The core physical mechanism for electrons to stably orbit the nucleus without orbital collapse is that the Coulomb electrostatic attraction between the nucleus and electrons, and the electromagnetic repulsion generated by the high‑speed orbital motion of electrons, always maintain a continuous, synchronous, instantaneous, and uninterrupted dynamic equilibrium. These two forces must change simultaneously with the electron’s position, distance, direction of motion, and orbital curvature at every moment. Any interruption, delay, or asynchrony of forces will immediately break the equilibrium, causing the electron to be attracted into the nucleus and resulting in the complete collapse of the atomic structure. Based on objective physical laws, this paper fully expounds the model of electrons in continuously variable quasi‑circular motion, clarifying that the continuity of force is the fundamental condition for atomic stability. This model is intuitive, self‑consistent, and logically rigorous, fully grounded in inertia and electromagnetic interactions, and can systematically explain the entire physical process of the stable motion of extranuclear electrons.
