Description

The electron orbitals of the hydrogen atom describe the wave-like behavior of an electron in atom and they determine the probability to find it in a particular space region. Mathematically the orbitals are determined by the hydrogen atom wave functions of its energy eigenstates and the wave functions themselves are determined as the solution to the quantum mechanical Schroedinger equation.

This app visualizes the electron orbitals of the hydrogen atom in 3D by drawing the cross-section surfaces of the electron probability density in OpenGL and using the Marching Cubes algorithm.

Features:
- Select the electron orbital to visualize by specifying the quantum number n, l and m, or pick the random one.
- Change the discretization step size.
- Choose the total probability to find electron inside the drawn orbital surface.
- Zoom and rotate the orbital with your fingers.

Comments on Hydrogen Atom Orbitals for Android

★★★★★ A Google User · Oct 11, 2015

Nice app® Amazingly useful for understanding the shapes of atomic orbitals.....but the "rotation feature" need some improvements!!!!

★★★★☆ Ravenclaw Avenger · Nov 12, 2017

This app shows orbital geometries for numerous atomic orbitals 3d on the orbitals take interesting shapes. The figure can be rotated and flipped to show more of the orbital. Just run your finger over the screen. Orbital lobes are some positive and some negative. Suggested app: show hybridized orbital such as sp², sp³, spd³ etc. There are many, some not so well known but giving interesting shapes

★☆☆☆☆ Atul Singh · Oct 15, 2019

Biggest bug: can't create orbitals of type n=2, l=0, m=0 and n>1, l>1, m=0 when percent is set to 99%.
