Atomic Theory and the Nuclear Model

In chemistry, the atomic theory is a theory of the nature of matter, which states that matter is composed of discrete units called atoms. The word "atom" comes from the Ancient Greek adjective atomos, meaning "indivisible". The word "atom" itself comes from the Greek , "indivisible". The word was coined by the ancient Greeks as a result of their philosophical theories on the nature of the universe. The word "atom" was first used by the early Ionian philosophers, who used the word to describe the smallest unit of matter that cannot be divided into anything smaller. This fundamental concept was further developed in the 6th century BCE by the Pre-Socratic Greek philosopher Leucippus, who claimed that atoms were the fundamental constituent of all matter. Leucippus and his student Democritus (c. 460–370 BCE) argued that the fundamental constituents of the world were indivisible atoms which were constantly moving and interacting in empty space until they assembled into the objects we see around us.
