The concept of the atom was proposed by ancient Greek philosophers Leucippus and Democritus in the 5th century BCE, suggesting that matter is composed of indivisible particles. The modern definition of an atom, as the smallest unit of a chemical element, was further developed by scientists like John Dalton, J.J. Thomson, and Ernest Rutherford in the late 19th and early 20th centuries.
