Explore electrons as probability clouds sampled from hydrogen wavefunctions — rotate s, p, and d orbitals, open cross-sections to find nodes, and compare shells side by side.
The “electron orbiting like a solar system” you often see in pictures of an atom is not its real form. The electron’s whereabouts are not pinned to one point; it wraps the nucleus as a gradient of likelihood — a cloud of probability. The specks of light before you are a record of “where it was found” after searching for the electron thousands of times. First, turn the cloud all the way around and confirm it is denser toward the centre.
Turn the cloud and confirm it is the same sphere from every direction, denser toward the centre.
