The theory was that all metals were made out of mercury and Sulfur and it might be possible to change base metals into gold.
-
plato was the one that introduced the atomic theory. in which ideal geometric forms of atoms which atoms break into triangles.
-
this theory had everything that had atoms which are physically but their not geometrically invisible.
-
Aristotle did not beileve in the atomic theory, He thought that everything was made out of the four elements.
-

-
Lavoisier work was the first breakthrough in the study of chemical reactions
-
Dalton said that al matter was composed of atoms witch are both invisible and indestructible building blocks. And different elements had atoms of differing size and mass.
-
