In Millie's stories, electrons look like little spheres with a funny pointy hat. But in real life, nobody knows what they really look like because they’re so tiny that we can’t see them. Some scientists think they might be like tiny spheres, others think they’re like little clouds, and some say they don’t have a shape at all because they are just a dot!
The truth is, it doesn’t really make sense to talk about the "shape" of an electron. Electrons are so small and weird that they don’t behave like things we see in everyday life.
Still, the way they’re drawn in Millie's books is super helpful because it shows you which way their spins are pointing — and that’s really important to understand how they work.
