Example:
Imagine trying to keep a balloon from touching the floor by continuously tapping it to stay in the air. Just like the balloon that hovers around you without actually landing, an electron orbits around the nucleus of an atom, never quite touching it. The way the balloon is kept aloft by your taps is similar to how the electron remains in constant motion due to its negative charge, which keeps it attracted to but not colliding with the positively charged nucleus, much like the hovering balloon that stays up but never touches the ground.

Electron: A negatively charged particle outside the nucleus of an atom, electron. An electron is a tiny particle that orbits the nucleus of an atom and carries a negative electric charge.
