Name all four points of Dalton's "Atomic Theory of Matter"
Elements are made of tiny indivisible particles called atoms.
All atoms of a given element are identical, but differ from those of any other elements.
Atoms of different elements can combine with others to form compounds.
Atoms cannot be created or destroyed in a chemical reaction, just rearranged.
