- a particle of matter that uniquely defines a chemical element
- comprised of three subatomic particles: protons (p+), neutrons (nĀ°), and electrons (e-)
- often thought of as the "building blocks of the universe", but now we know that you can go even smaller, by breaking atoms down into "quarks".
