It is difficult for us to imagine the three-dimensional appearance of atomic orbitals from the formulae of the solution of Schroedinger wave equation . In this paper, we would like to report the visualization of three-dimensional contour surfaces of a series of hydrogen atomic orbital functions using a software called AVS (Application Visualization System) on an EGWS ( Engineering Graphic Workstation ), IRIS INDIGO XS24 or TITAN 3000. From these drawings, the relationship between the number of lobes and nodes of atomic orbitals was derived .
