Dalton's atomic theory.
The ancient Greeks thing that the matter consist in simple units, and this unit was called Atom.
They think that the Atom is unique and indivisible, we cannot divide more and all the matter consisted in that. His theory really was true, but they hadn't tested that theory until John Dalton. John Dalton was burn in the Eagles field city, in England. He tested many postures of his own hypothesis, he tested and public. The many ideas were published and they are:
- All matter is composed of atoms
- Atoms cannot be made or destroyed
- All atoms of the same element are identical
- Different elements have different types of atoms
- Chemical reactions occur when atoms are rearranged
- Compounds are formed from atoms of the constituent elements.
But, however always have to be a mistake, and he is not exception. He had sick on his eyes, a rare sick in his eyes, he suffer colorblind, and he was confused with his experiment and the color of this. The name of this sick is called too Daltonism.
