History & Origin
The word atom comes from ancient Greek atomos (ἄτομος), meaning 'indivisible' or 'that which cannot be cut'. Greek philosopher Democritus coined it around 400 BC to describe his theory of matter's fundamental building blocks. The concept shaped the entire trajectory of chemistry and physics from Dalton's atomic theory (1803) onward.
As a given name, Atom is rare but appears in various cultures — in Japan as Atom (アトム), it is the name of the iconic manga character Astro Boy (Tetsuwan Atom), created by Osamu Tezuka in 1952. In the Western naming tradition it is an unconventional choice with a strong conceptual identity.
