Option C. Defines the exact path of an electron around the nucleus. The theory is based on electrons as matter waves using the de Broglie wavelength, the Schrödinger equation, and the Heisenberg uncertainty principle. We study the spin of the electron and the Stern-Gerlach experiment. Three scientists settled these theories, in 1924, Louis de Broglie, postuló that the electrons had a dual behavior of wave and particle. In 1927, Werner Heisenberg, suggests the "uncertainty principle". In 1927, Erwin Schrödinger establishes the behavior of an electron in the atom. This function is called electron density and indicates the probability of finding an electron near the nucleus.
