Dalton’s atomic theory
> atoms of a given element are identical in size, mass, and other properties
all matter is composed of extremely small particles called atoms
atoms cannot be subdivided created or destroyed
atoms of different elements combine in simple whole number rations to form chemical compounds
in chemical reactions, atoms are combined, separated, or rearranged.
a chemical compound always contains exactly the same proportion of elements by mass
law of definite proportion
