I know but i wont tell you <3
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.
The Greeks, from the word atomon, meaning "uncuttable, indivisible."
British Physicist Ernest Rutherford is considered the 'father of nuclear physics' and is credited with splitting the first atom in 1917. He pioneered the Rutherford model of the atom and theorized that the charge of an atom is concentrated into a nucleus. He was able to split the atom in a nuclear reaction between alpha and nitrogen particles which led to the discovery of the proton.
Rutherford's experiment was important because it showed that an atom is mostly empty space. Rutherford gave more detail of the atom's structure.

Aristotle did not discover the atom. The concept of the atom was first proposed by the ancient Greek philosopher Leucippus and his student Democritus around the 5th century BCE. Aristotle, who came after them, did not accept the idea of atoms and instead favored a different view of matter.
Very many, and much to say about all of them. Try these in Wikipedia for a start: Aristotle, Dalton, Rutherford, Geiger and Marsden, Chadwick, Bohr.

Aristotle.
Nothing.
His MAJOR discovery was when he discovered the atom.

Aristotle did not discover the atom. The concept of the atom was first proposed by the ancient Greek philosopher Democritus around the 5th century BCE. Aristotle had a different view of matter, which did not involve indivisible particles like atoms.

Aside from philisophical contributions, Aristotle created the empirical system in science of categorization based on observation.
the ancient Greeks made the atom, but they had no proof after the discovery.
