A novel model of atomic structure — the electronium model,based on the Schrdinger equation,was developed by bringing in a new concept of electronium.The new model is much closer to our everyday experience with its two specially defined quantities,i.e.the electronium density and current density,which can clearly express various states of a hydrogen atom (eigenstates and superposition states).Moreover,it has a much better operability as it can conveniently be operated and applied.In virtue of this model,the solutions of the Schrdinger equation can be visualized with computer,and it is possible that the pictures of various states of a hydrogen atom and animations of the transitions from one eigenstate or stationary state to another are distinctly demonstrated.Thus various properties or phenomena of the atom can directly and readily be explained.Therefore,it is expected that the electronium model should be conducive to improve the teaching and research of quantum physics.
