What did the Greeks name to be the tiniest particle of matter?
an atom
What did the greeks believe about atoms?
The word Atom comes from the Greek a-tomos meaning uncuttable. Name by Democritus, who belived that matter is not continuous but made of tiny, indivisible grains of material, The Atom. We now know that this is not true as atoms are constructed from various ratios of protons & neutrons (which in turn as made up of quarks), and electrons.
How did J.J. Thomson's discovery affect the model of the atom?
J.J. Thomson is credited with the discovery of the electron in about 1904. He envisioned negatively charged "corpuscles" floating in a positively charged cloud, just like plums in a plum pudding. This was the "plum pudding" model of the atom, and it lasted until Geiger and Marsden conducted their gold foil experiment in about 1909.

Were democritus's views of the atom based on experimental evidence?
No, he theorized that there was a small indivisible particle (he called the "atom" because it means indivisible), but he never did any experiments to prove his theory. Around the same time, Aristotle believed that matter could be divided infinitely. Both were considered speculation until the eighteenth century.
How did the discovery of electrons show that there are also positively charged of the atom?
The discovery of the electron proved the positive charge of the atom when sending an electric spark across an air gap from one electrode to another, called the photoelectric effect.
