Final answer:
Atomism, originating from ancient Greek philosophers, introduced the concept of indivisible particles known as atoms, which was later refined with the discovery of subatomic particles like electrons.
Explanation:
Atomism is a concept that originated with the ancient Greek philosophers Democritus and Leucippus around the fifth century BC. The term atom, derived from the Greek word 'atomos,' meaning indivisible, was used to represent the idea that matter is composed of small, unbreakable particles. However, this belief was later refined when J.J. Thomson discovered subatomic particles such as electrons, showing that atoms are not truly indivisible.
