TY - JOUR AU - Xiao En Wang PY - 2024 DA - 2024/10/18 TI - On the Atomic Structure JO - Japan Journal of Research VL - 5 IS - 11 AB - In recent years, it has been recognized that treatment of the spectral problem should be associated with closed orbits. This paper proves that the closed orbit obtained by Bohr using numerical algebraic equation is reasonable both mathematically and physically and that the de Broglie wavelength of the electron in the hydrogen atom is equal to the circumference of its orbit. By Bohr model and de Broglie’s matter-wave thought, some quantization conditions, electronic transition formulae, a mechanism and details of emitting photon wave train, a filling order of electrons in the periodic table, and Madelung rule have been deduced theoretically. We solve the Löwdin’s challenge problem. SN - 2690-8077 UR - https://dx.doi.org/10.33425/2690-8077.1151 DO - 10.33425/2690-8077.1151
