Drag inside the chamber to rotate the 3D field map. Drag outside the ring to pan. Transparent planes or cones mark zero-probability angular nodes.

Each marker is a separate, identically prepared atom—not a trail from one electron.

Radial probe 2.00 a₀

Tap the nucleus, cloud, node, detector ring, coil, or radial scanner for its role.
