He shared the 1933 Nobel Prize for Physics with British physicist P.A.M. Dirac. A powerful model of the atom was developed by Erwin Schr�dinger in 1926. Erwin was born August 12, 1887 in Austria.

The postulates of Schrödinger's atomic model are the following: -The electrons behave as standing waves that are distributed in space according to the wave function Ψ. This model is seen and understood as a nucleus surrounded by an electron cloud. He attended the University of Vienna and after attending this college in 1926 her came up with his own wave equation to explain the distribution of electrons in an atom. En imaginant l'équation d'évolution de la fonction d'onde associée à l'état d'une particule, il a permis le développement du formalisme théorique de la mécanique quantique. Schrödinger defined the waves that describe electrons as stationary or orbital states, and are associated, in turn, at different energy levels.

Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. The Schrödinger equation indicates that if we have a wave function Ψ, and the Hamiltonian operator acts on it, the proportionality constant E represents the total energy of the quantum system in one of its stationary states. Cette proposition est connue sous le nom de modèle mécanique quantique de l'atome et décrit le comportement ondulatoire de l'électron. For this, the outstanding Austrian physicist was based on the hypothesis of Broglie, who stated that each particle in motion is associated with a wave and can behave as such. https://timelineoftheatom.blogspot.com/p/erwin-schrodinger-1926.html La probabilité visée est proportionnelle au carré de la fonction d'onde 2.La configuration électronique du modèle atomique de Schrödinguer explique les propriétés périodiques des atomes et les liaisons qu'ils forment.Cependant, le modèle atomique de Schrödinger ne considère pas le spin des électrons, pas plus qu'il n'envisage les variations du comportement des électrons rapides dues à des effets relativistes. Ainsi, lorsqu’elle a été placée horizontalement, le faisceau a été divisé en deux parties à peu près égales. Schrödinger, who was awarded the Nobel Prize in 1933 for his contributions to atomic theory, developed the homonymous equation to calculate the probability that an electron is in a specific position. Quantum MECHANICAL MODEL OF THE ATOM In 1926, Schrödinger took the Bohr Atom model further and calculated a mathematical equation to discover the probability of an electron occurring in different places or in a certain position. There was evidence of the interference pattern between both waves, which showed that light could behave as both a particle and a wave. It only establishes a probability zone to locate the electron. This atomic model is known as the quantum mechanical model of the atom. distribution of electrons in the atom. For this, Schrödinger relied on Young's experiment, and based on his own observations, developed the mathematical expression that bears his name. The only information that was important was the The three coordinates that come from Schr�dinger's wave equations are the principal ( Orbital 1s, 2s and 2p within a sodium atom. -The electrons move within the atom in describing orbitals. Electrons are constantly moving and cannot be given a definite position within the atom. Introduction to the quantum mechanical model of the atom: Thinking about electrons as probabilistic matter waves using the de Broglie wavelength, the Schrödinger equation, and the Heisenberg uncertainty principle. It only establishes a probability zone to locate the electron. However, the Schrödinger atomic model does not contemplate the spin of electrons, nor does it consider the variations in the behavior of fast electrons due to relativistic effects. This implies that the wave does not move, its nodes, that is, its points of equilibrium, serve as a pivot for the rest of the structure to move around them, describing a certain frequency and amplitude. Instead of The Schrödinger equation independent of time is as follows: The time-independent Schrödinger equation is used when the observable representing the total energy of the system, known as the Hamiltonian operator, does not depend on time.

probability that an electron can be found in a given region of space at a given time. Pour cela, l'excellent physicien autrichien s'est basé sur l'hypothèse de Broglie, qui a déclaré que chaque particule en mouvement est associée à une onde et peut se comporter comme telle.Schrödinger a suggéré que le mouvement des électrons dans l'atome correspondait à la dualité onde-particule et que, par conséquent, les électrons pourraient être mobilisés autour du noyau sous forme d'ondes stationnaires.Schrödinger, qui reçut le prix Nobel en 1933 pour ses contributions à la théorie atomique, développa l'équation du même nom pour calculer la probabilité qu'un électron se trouve dans une position spécifique.-Décrit le mouvement des électrons comme des ondes stationnaires.-Les électrons se déplacent constamment, c'est-à-dire qu'ils n'ont pas de position fixe ou définie dans l'atome.-Ce modèle ne prédit pas la position de l'électron, ni ne décrit la route qu'il fait dans l'atome.
