What are protons, neutrons, and electrons?
Three-Piece Universe
What are protons, neutrons, and electrons?
Pick up anything — this book, your hand, a cup of cold water. Zoom in. Zoom in MORE. Past the point where your eyes can follow. Eventually you hit the tiniest LEGO brick the universe builds with: the atom. And every single atom, no matter what it makes up, is built from just three kinds of pieces.
Meet the crew. There are protons, neutrons, and electrons. That's it — three characters playing every role in the entire material world. A tree, a star, a sandwich, you: all of it is just these three, stacked in different amounts. Think of them as three actors who keep getting cast in every movie ever made.
