Timeline Of The Evolution Of The Atomic Theory

Higgs particles (or God particles) were inferred by Peter Higgs in 1964. Recently, this idea was discovered by the European Atomic Energy Research Center in 2012. It proves the existence of the Higgs field, and God's particles say that it gives other particle blocks

Higgs field occupies all of the universe. It is regarded as molasses and can trail particles through it. Particles that receive mass interact with Higgs particles. Therefore, the electron mass which hardly interacts with the electric field is very small, protons and neutrons interacting with it have more mass than usual.

The presence of God's particles was demonstrated at the European Atomic Energy Research Center's large hadron collider. Some protons are crushed together to release energy; since Einstein 's relativity theory believes that the mass is energy and energy can not be destroyed, new particles will be released from energy release It is produced. Higgs particles are unstable, so they split into more particles. This rare condition is detected by the collider's sensor. This is rare as there are trillions of conflicts

Timeline description: Atomic theory is the scientific theory of the nature of matter. The theory thinks that the substance consists of small particles called atoms. Before this theory, it was thought that substances could be divided into any small amount. The word atom is derived from the atmosphere of Greece and means indivisible. Neils Bohr has developed a Bohr atomic model. In this model, electrons run in the orbit of the nucleus and the chemical properties are determined by the number of electrons in the outer orbit. He also integrated Plank 's quantum theory, pointed out that as the electrons change orbits they release some degree of discrete energy.

Neil Boah contributed to chemistry and physics. Bohr model - the theory that electrons move in discrete orbits around nuclei, the shell model of atoms - the chemistry of elements is determined by the electrons of the outermost orbitals. Correspondence Principle - Determine the fundamental tools of old quantum theory, nuclear droplet model, uranium isotope that causes slow neutron fission, many studies on Copenhagen quantum mechanics, and principle complement - these There are several items analyzed separately.

With the emergence of quantum mechanics and Schrodinger equation in the 1920's, atomic theory became accurate mathematical science. Austrian physicist Erwin Schchöderer designed partial differential equations for the quantum mechanics of atomic electrons, including the electrostatic repulsion for all negatively charged electrons and the attraction to the positively charged nuclei. This formula allows you to solve atoms containing only one electron (hydrogen) exactly, and you can find an approximation very close to atoms containing two or three electrons (氦 and lithium). To some extent, the Schrödinger equation can solve more complicated situations, and atomic theory can predict the nature of all atoms and their interactions from the first principle. If a slight correction due to special relativity and the influence of quantum electrodynamics theory is also included, accurate consistency with the experiment can be obtained.
