Democritus proposed the first atomic theory, suggesting that matter is made up of indivisible particles called atoms. Thomson's model, proposed in the late 19th century, introduced the idea of the atom as a sphere with embedded electrons, challenging the indivisibility of atoms seen in Democritus's model and suggesting the presence of subatomic particles. Thomson's model also laid the groundwork for the later development of the more accurate planetary model of the atom by Rutherford.
