Answer:
Atoms seek more stable states. The structure of an atom is similar to that of the solar system. The large protons (with a positive charge) and neutrons (with no charge) are found at the nucleus or center. The tiny electrons (with negative charges) circle rapidly in orbits around the nucleus, forming electron shells at different distances, much like the planets and other objects that circle the sun. Atoms of each element have varying numbers of electrons in their outermost shells.
