Combining the idea of quantization and the semi-classical hydrogen model of Bohr, the structure of atom is described. Solving the Schrodinger equation, the deduced wave function is related to the probability of finding the electron in space, a particle in the potential well and in a box. The concept of atom is expanded to the molecular and the energy band theory of solid state physics.
