Democritus was one of the first people to state the idea that all matter is made of tiny, separate particles. He believed that atoms were indivisible, and that each substance was made of its own type of atom, linked together in various different ways, e.g. atoms of iron were connected strongly, but those of water more weakly. He used the word atom in a rather different way than we do. In some ways our word 'molecule' is closer to his concept.
The word "atom" comes from the ancient Greek word "atomos," meaning indivisible. It was introduced by the Greek philosopher Democritus in the 5th century BC. However, the modern understanding of atoms and their structure was developed through the work of scientists like John Dalton, J.J. Thomson, and Ernest Rutherford.
The Greeks, from the word atomon, meaning "uncuttable, indivisible."
The first Greek philosopher to propose the concept of an atom was Democritus. He believed that all matter is composed of tiny, indivisible particles called atoms. Democritus's ideas laid the foundation for the development of modern atomic theory.
John Dalton in 1803
An atom is the basic unit of matter, consisting of a nucleus containing protons and neutrons, surrounded by electrons. The concept of the atom was first proposed by ancient Greek philosophers such as Democritus and Leucippus, but modern understanding of the atom was developed in the late 19th and early 20th centuries by scientists like J.J. Thomson, Ernest Rutherford, and Niels Bohr.
The atom was not discovered by Democritus; Leukipus an Democitus proposed the notion of atom, but only intuitively, not experimentally.

An atom is an indivisible part of all matter.

Democritus did not have experimental evidence to support his idea of the atom. Instead, his idea was based on philosophical reasoning and speculation.
