Electron

atoms · electricity · science

Negative charge carriers. Electrons are incredibly tiny bits of matter that carry negative electrical charge. They're so small that billions of them could fit on the head of a pin.

Everywhere in atoms. Every atom in your body contains electrons spinning around a center called a nucleus. Electrons are what make atoms stick together and form all the materials around you.

Creates electricity. When electrons move from one place to another, they create electric current. This flowing movement powers everything from lightbulbs to video game controllers.

Elementary particle. An electron is one of the most basic building blocks of matter that scientists know of. Scientists can't break an electron into smaller pieces.

Makes chemistry work. When electrons move between atoms, they cause chemical reactions that power everything from your muscles to fireworks. This is why understanding electrons helps explain how the world works.
