Abstract: According to the characteristics of abstract and hard to understand of electronic probability density in hydrogen atom in quantum physics, this paper suggests the distributed function of electronic probability density in hydrogen atom including the radial distribution function and angular distribution function. We investigate the distri- bution law of electronic probability density for visualization by using powerful drawing function of Matlab. The re- sults show that the method reveals the distribution of electronic probability density in hydrogen atom intuitively and vividly. It provides a new way in physics teaching.
