Q:
picture of the greek model of the atom
- Anonymous
A:
Democritus pictured atoms as solid little objects that came in all different shapes. The different shapes accounted for all the different ways they could stick together to make different materials. This model was never very popular among the ancient Greeks.

Here's a link to a more detailed historical discussion:

Follow-Up #1: original Greek atoms

who invented the greek atom?

A:
It's hard to know who thought of what first, but I believe that Leucippus was the first  person we know about who said everything is made of atoms. Democritus was perhaps the most important advocate of this idea.

It's important to realize that the things we now call 'atoms' wouldn't have qualified for the Greek name, which means 'uncuttable'. The things  we call atoms can be broken into electrons and nuclei, and the nuclei are further breakable into protons and neutrons. It's a historical accident that the name 'atom' got attached to things which were very briefly not known to be divisible.
