Dalton’s Atomic Theoryhttp://en.wikipedia.org/wiki/John_Dalton

• Five main points of Dalton's atomic theory• Elements are made of extremely small particles called atoms.• Atoms of a given element are identical in size, mass, and

other properties; atoms of different elements differ in size, mass, and other properties.

• Atoms cannot be subdivided, created, or destroyed.• Atoms of different elements combine in simple whole-

number ratios to form chemical compounds.• In chemical reactions, atoms are combined, separated, or

rearranged.

Rutherford Quote

• “It was almost as if you fired a 15 inch shell at a piece of tissue paper and it came back and hit you”
