Short answer question.

1. John Dalton, J.J. Thomson and Ernest Rutherford each had their view of the atom. Sketch each of their views of the atom. Briefly describe each. 2. State the law of conservation of mass. How does Dalton's atomic theory explain the conservation of mass. 3. State the law of definite proportions. How does Dalton's atomic theory explain the law of definite proportions? 4. State the law of multiple proportions. How does Dalton's atomic theory explain the law of multiple proportions? 5. How and by whom was the electron discovered? What basic properties of the electron were reported with its discovery? 6. How did Rutherford's experiment (the Gold Foil Experiment) prove that the plum pudding model of the atom was wrong? 7. If matter is mostly empty space, as suggested by Rutherford, then why does it appear so solid? 8. List the three subatomic particles that compose atoms and give the basic properties (mass and charge) of each. 9. How can we revise Dalton's atomic theory to include what we know now about atomic structure? (I have inserted the power point slide that shows Dalton's atomic theory as well as the slide which shows the revision into this document to help you.)
