A negatively charged, diminutive ball of motion. Kind of like some cats I know.
Electron is also part of the Lepton 6-pack, Everyday Matter 6-pack and Atomic 3-pack.
Approximately 0.6 oz/16 grams; 4 inches/10 cm across.

Made in China. Age 3 and up. Along with the Higgs boson, this is currently the only member of the Zoo who is not handmade. We hope you don't mind. If you MUST have a handmade electron, just email us (but it won't have the nifty "e-" symbol on the back.)
