The electrical nature of the particles that make up the atom allows the prediction of the electromagnetic emission spectrum, resulting from the mechanics between the particles involved. However, the radiation process described by quantum physics is different from the understanding made by ordinary electromagnetism. The understanding of fission is discussed by the correspondence principle.The proposed curvature produced by the elementary electric charge and the representation by an electrometric tensor make it possible to address aspects of classical and quantum theories using the same formulation. The electron does not fall into the nucleus, as it follows a geodesic trajectory. The resolution of the atomic binary system encounters self-induced harmonic oscillations that produce fluctuations in the metric, with consequences in the determination of the point representation and in the position-momentum simultaneity in the same reference frame. The energy of the orbital transition by the electron, according to the spectrum of the hydrogen atom, reproduces the discretization and ripple effects as a consequence of the resolution. The result endorses how the correspondence between electromagnetic radiation processes is understood by electrometric curvature.
