Dalton's theory does NOT explain:
Why matter is charged
That elements cannot be converted into new elements
Similarity/difference of atomic properties
That atoms cannot be divided
10
Why should scientists continue to investigate the atom and atomic theory?
New discoveries change previous ideas
Different approaches yield different results
To continue to build knowledge
All of the above
