He discoverd the five solids known as platonic solids. Plato (427 B.C.E) Plato introduced the atomic theory in which ideal geometric forms serve as atoms, according to which atoms broke down mathematically into triangles, such that the form elements had the following shape: fire (tetrahedron), air (octahedron), water (icosahedron), earth (cube).

Democritus and Empedocles were Pre-Socratics, a group born before Socrates that also includes: Thales, Anaximander, Anaximenes, Parmenides, Heraclitus, Anaxagoras, Zeno, Pythagoras. Plato had two brothers and a sister. Democritius model is the earliest of the atomic models written down. Timeline Description: Atomic theory is the scientific theory of the nature of matter. atomic model timeline project. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties. The modern atomic theory, proposed about 1803 by the English chemist John Dalton (Figure 1.5. 4 ), is a fundamental concept that states that all elements are composed of atoms . Previously, an atom was defined as the smallest part of an element that maintains the identity of that element. Democrituss atomic theory stated that all matter is made up of small units called atoms which cannot be destroyed.
