The atomic theory has been developed over many years due to the work of many scientists. Each time now evidence was discovered changes had to be made. Which of the following statements is true about how new evidence affects theories?
As new evidence is found, the evidence is changed to make it better fit the existing model,
As now evidence is found, the theory is revised in order to make it fit the data botter
As now evidence is found, the theory is discarded completely and scientists start over with a completely now theory
As new evidence is found a new theory is introduced that does not fit the data as well

Explanation:

Chemistry is full of unanswered questions. One of the first questions people have been asking since ancient times is What is the world made of?

That is, if we were to zoom in ~100000000000 times—that is 11 zeros!—on the skin of your fingertip, what would we see? Would that look any different from zooming in on, say, an apple? If we then cut up the apple into tinier and tinier pieces using an imaginary tiny knife, would we reach a point where the pieces could no longer be cut any smaller? What would those pieces look like, and would they still have apple properties?

The answers to these questions are fundamental to modern chemistry, and chemists didn't agree on the answer until a few hundred years ago. Thanks to scientists such as John Dalton, modern chemists think of the world in terms of atoms. Even if we can't see atoms with our naked eye, properties of matter such as color, phase (e.g., solid, liquid, gas), and even smell come from interactions on an atomic level. This article will discuss John Dalton's atomic theory, which was the first complete attempt to describe all matter in terms of atoms and their properties.
