Quantum Atomica is a free program developed specifically to help visualize hydrogen orbitals in a variety of ways. This is done by plotting the solutions to Schrödinger’s Equation.

It allows the user to visualize the complete set of hydrogen orbitals up to and including those for which the quantum number ‘n’ is equal to 4. Quantum Atomica is aimed at teachers teaching physics or chemistry in secondary schools but will also be useful to undergraduate students studying chemistry in college.
