Word origin
The word 'atom' originates from the Greek word 'atomos', meaning indivisible. The concept of atoms as the fundamental building blocks of matter dates back to ancient Greek philosophers such as Democritus. In the 19th century, John Dalton developed the modern atomic theory, which proposed that elements are composed of small, indivisible particles called atoms. The discovery of subatomic particles like protons, neutrons, and electrons further expanded our understanding of the structure of atoms.
