The physical model of elementary particles, based on the wave features of their behavior, is described here. Elementary particles are regarded as elementary dynamical structures of the microworld, interrelated with all levels of the Universe, i.e., inseparable from the structure of the Universe as a whole. Between any elementary particles and the ambient field of matter-space-time, as well as between elementary particles themselves, there exists an interchange of matter-space-time occurring both in horizontal (within the same level) and vertical (between different levels) directions. This model allowed revealing the nature of mass and charge of elementary particles that is described here along with other important results originated from such a model
