Influence on Atomic Theory - He was the starting point for Atomic Theory.

His Theory - That everything was made up of tiny particles that had similar properties to their whole.

Right and Wrong -

•  Right : Everything is made up of small particles.
•  Wrong : These "A-tomos" are much more complex and are different from their whole.

Influence on Atomic Theory - John Dalton proposed the actual Atomic Theory.

His Theory - That there are three different types of matter. Elements, compounds, and complex molecules.

Right and Wrong -

•   Right : Right about there being several types of matter that make up certain substances.
•  Wrong : Wrong about atoms being the final shapes and indivisible, they can be divided into things like electrons, protons, etc.

Influence on Atomic Theory - He discovered electrons.

His Theory - His theory was that these electrons were distributed around randomly, compared to plum pudding.

Right and Wrong -

•  Right : These electrons did exist and were responsible for what many atoms do.
•  Wrong : The electrons weren't placed quite the way that he thought.

Influence on Atomic Theory - He developed the "Bohr Model", which influenced the development of Atomic Theory for years to come.

His Theory - That the electrons circled the nucleus in a circular orbit.

Right and Wrong -

•  Right : The electrons do orbit the nucleus.
•  Wrong : They were not as precise as he thought.

Influence on Atomic Theory - He helped develop Quantum Theory and disprove Bohr's model.

His Theory - That Bohr's model was wrong, and that there was only a probability of finding an electron in certain areas.

Right and Wrong -

•  Right : The current model he created is currently accepted as the official model.
•  Wrong : We still don't really know if it is completely true.

Influence on Atomic Theory - Discovered and proposed the idea of the Nucleus.

His Theory - Inside each atom lies a nucleus in the center.

Right and Wrong -

•  Right : There is indeed a nucleus in the middle of an atom.
•  Wrong : Rutherford failed to create a sensible model with this data and couldn't explain some factors of his model.
