John Dalton proposed atoms as indivisible spheres, J. J. Thomson discovered electrons and introduced the plum pudding model, Ernest Rutherford found the nucleus in his gold foil experiment, and Niels Bohr developed the Bohr model with quantized electron orbits. These models collectively led to the current quantum mechanical model of the atom, which describes electrons in probabilistic orbitals around the nucleus.

Rutherford’s gold foil experiment revealed that atoms have a dense nucleus, suggesting that most of the atom is empty space, which laid the groundwork for the planetary model later refined by Bohr. J.J. Thomson’s “plum pudding” model introduced the idea of electrons embedded within a positively charged sphere, while Dalton’s atomic theory offered the concept of indivisible atoms. Over time, these advancements combined to form the quantum mechanical model, where electrons exist in probabilistic clouds around the nucleus rather than fixed orbits.
Rutherford proposed that an atom consists of a tiny, dense nucleus surrounded by orbiting electrons. J.J. Thomson introduced the idea of electrons being sprinkled throughout a positively charged “soup,” forming the plum pudding model. John Dalton’s model suggested that atoms are solid, indivisible spheres, while Niels Bohr modified Rutherford’s model by quantizing electron orbits, implying that electrons can only exist at certain energy levels. Each contributed building blocks that brought us closer to our modern understanding of atomic structure!
