Question

Which statements belong to Dalton’s atomic theory ? Select all that apply.

Answer 1

All atoms of an element are identical. 
Chemical reactions cause atoms to be rearranged. 
And maybe Atoms cannot be created or destroyed. He said they were the smallest so I guess he meant they couldn't be destroyed or broken down. 

At Daltons time, they didn't know about protons, electrons and neurtons or a nucleus.
