Whose model described the atom?

In 1911 Ernest Rutherford showed that atoms have a tiny, dense, positively charged nucleus at their centre, based on experiments firing particles at gold foil. Building on this, in 1913 Niels Bohr proposed a model in which electrons orbit the nucleus in fixed energy levels, jumping between them by absorbing or releasing energy. The Bohr model successfully explained the light emitted by hydrogen. It was later replaced by the more accurate quantum mechanical model, in which electrons occupy fuzzy clouds of probability rather than neat orbits. Still, the Bohr picture remains a useful and widely taught introduction to atomic structure.
