This application shows the graph of the probability density function of hydrogen orbitals.

If you're on a mobile device, use the usual touchscreen gestures to manipulate the chart:

• Tap and drag with one finger: zooms in on the selected region.
• Two clicks: returns to the original graph after zooming.

Buttons:

• Configures other application parameters: plane to be plotted, graph resolution, scale (linear or square root) and color map (blue/red or grayscale).

The two-dimensional graph shows the probability density function, that is, the square modulus of the wave function, based on the stationary states of the hydrogen atom

$$ \psi_{nlm}(r, \theta, \phi) = C_{nlm} e^{-r/na_0} \left( \dfrac{2r}{na_0} \right)^l \times $$ $$ \times L_{n-l-1}^{2l+1} \left( \dfrac{2r}{na_0} \right) \times Y_l^m(\theta, \phi) $$

Only the three main planes ($x = 0$, $y = 0$ and $z = 0$) are available for the plot.
