All atoms are made of tiny particles called subatomic particles: protons, neutrons, and electrons. Each has a different electric charge. Protons are positive, neutrons have no charge (they are neutral), and electrons carry a negative charge.

Electrons are much smaller than protons or neutrons and move around the center of the atom in orbits. This central part is called the nucleus, and it contains protons and neutrons. The electrons do not stay still—they are always moving around the nucleus in what is called the electron cloud.

The negative charge of electrons is important in many things. It helps atoms bond together, allows electricity to flow in wires, and is used in many electronic devices we use every day. Without electrons, there would be no current, no light bulbs, and no smartphones.

So, if you ever need to remember which particle has a negative electric charge, just think of the tiny electron. It might be small, but it plays a big role in science and technology.
