One of the most intriguing concepts that caught the imagination of Plato around the time of 350 B.C. was the existence and uniqueness of the five regular solids, which are now known as the five "Platonic solids". It is not certain who first discovered these regular solids first, but many believe that it was spoke of as early as the Pythagoreans. However, sources including Euclid indicate that Theaetetus, a friend of Plato's, was the first to write the first complete account of these five shapes. Plato's theory ultimately constructs the basis for what is to be Book XIII of Euclid's Elements. Plato, in any case, was extremely impressed by these definitively regular solids, and later on in life was intrigued to write his theory of everything in relation to these five polyhedrons. (Devlin 115) The most intriguing aspect of these shapes to Plato at the time was that these were the only shapes that constituted perfect symmetry within a non-planar set of points. The names of these shapes are the hexahedron (cube), tetrahedron, octahedron, icosahedron and the dodecahedron. It is very clear that each of the sides of these polyhedrons must not only be a regular polygon, but must be equal to ever
Atomic Theory
That the cake is a lie.
Benjamin Franklin's contribution to the atomic theory was his proposal that electricity was a fundamental force that could be understood through atomic models. He conducted experiments with electricity and proposed the idea of positive and negative charges, which later contributed to the development of the atomic theory.
The most important contribution of Werner Heisenberg was the discovery of the uncertainty principle.
Antoine Lavoisier was a French nobleman and chemist. His contribution to the development of the modern atomic theory was his idea of the possibility of an Atomic Mass.
Plato's greatest contribution was his development of the theory of forms, which suggests that abstract concepts like beauty and justice exist as perfect, unchanging ideals in a separate realm. This theory profoundly influenced Western philosophy and laid the groundwork for many future philosophical developments.

The contribution of anyone prior to about 1600 to the development of atomic theory might as well be "nothing whatsoever." Democritus and/or Leucippus contributed the name "atomos", but not much else; they were wrong about nearly every detail. John Dalton is just about the earliest scientist to have had any significant contribution to atomic theory, and most of what we now consider atomic theory was developed since about 1900.
he helped the creator of electrons and the studier of chemistry
James Chadwick discovered the neutron in 1932.
Mendeleeve formulated the Table of the Elements by listing them by their atomic weight and grouping them into 'families', with similar characteristics.
