1. The Balloon Shapes (Blue, Yellow, and Rainbow)

Electrons don't fly in flat circles like racecars on a track. They zoom around the center of the atom in really funky 3D shapes!

Some of their paths look like round balls.

Some look like two balloons tied together.

Some even look like four-leaf clovers or donuts!

Scientists call these shapes "orbitals," which is just a fancy word for the electron's neighborhood.
