The idea of atoms was first introduced by the ancient Greek philosopher Democritus in the 5th century BC. Democritus proposed that all matter is made up of tiny, indivisible particles that he called "atomos," meaning "uncuttable" in Greek.
Niels Bohr's work introduced the idea of quantized energy levels in atoms, which explained the stability of certain electron orbits. He also proposed that electrons orbit the nucleus in specific, fixed paths, creating the basis for the Bohr model of the atom.
