What are electrons doing as they move around an atom?
Picture a tiny atom, and right in the middle, a dense little knot called the nucleus. Around it, somewhere, are the electrons. Now, you might imagine them whizzing around like planets circling the sun. It's a lovely picture. It's also wrong — and the truth is far stranger and more fun.
For a long time, even scientists drew electrons as little balls on neat circular tracks. But when they looked closer, the tracks vanished. An electron doesn't roll along a path you can trace. Instead, it behaves like something blurry — part tiny particle, part spread-out wave, refusing to sit still in one spot.
