Calculating the Position of Electrons Around the Nucleus: Demonstrating the Orbital Shape of Hydrogen Atom and Helium Atom

Atomic orbitals are the basic building blocks of the atomic orbital model (alternatively known as electron cloud or wave mechanics model), a modern framework for visualizing the submicroscopic behavior of electrons in matter. In this model the electron cloud of a multi-electron atom may be seen as being built up (in approximation) in an electron configuration that is a product of simpler hydrogen-like atomic orbitals.
