Here's a breakdown:

* Nucleus: At the center of every atom is the nucleus. It contains protons (positively charged particles) and neutrons (neutral particles).

* Electrons: Electrons are negatively charged particles that orbit the nucleus.

* Attraction: The opposite charges of the protons and electrons create an electrostatic attraction, keeping the electrons bound to the atom.

Think of it like a tiny solar system: the protons in the nucleus are like the sun, and the electrons are like planets orbiting around it.
