The structure of atoms is known through a combination of experiments and theoretical models over centuries. Ernest Rutherford's gold foil experiment revealed a dense nucleus, while Niels Bohr proposed electrons orbit like planets. Quantum mechanics advanced our understanding, with Heisenberg's Uncertainty Principle and Schrödinger's wave equations explaining electron behavior. Advanced tools like X-ray crystallography and electron microscopes further confirm atomic structure.
