The invention belongs to the technical field of electronic orbital analysis and calculation, and particularly relates to a method for calculating an electronic orbital and an energy state in atoms. The method comprises the following steps: firstly, constructing an
electron kinetic equation, namely external force borne by electrons,
electron mass, acceleration of the electrons, internal force of the electrons, and displacement representing an
electron center position deviating from
inertial motion, and finally obtaining an
electron motion equation as shown in the specification; by solving the motion equation, orbits and energy levels of electrons in atoms, structures and energy states of molecules and physicochemical properties of
semiconductor materials can be calculated. According to the method,
hydrogen atoms are taken as an example, and the motion trail and the electron track of electrons in the
hydrogen atoms are calculated and described. The method can be expanded to analysis and research of energy states of electrons in molecules or crystals or vacuum and physicochemical properties of materials.
