Orbital shapes
Real hydrogen orbitals drawn as clouds of dots, with their nodes.
Open the interactive simulation →How to use this simulation
- Tap an orbital button (1s, 2p, 3d …).
- Rotate the cloud; blue and orange show the two signs of ψ.
- Read the nodes and look at the radial distribution graph.
What to notice
- Total nodes = n − 1; angular nodes = l.
- The 1s peak sits exactly at the Bohr radius, 52.9 pm.
