Dalton's atomic theory includes which idea? a. all atoms of all elements are the same size. b. atoms of the same element are always identical. c. individual atoms can be seen with a microscope. d. atoms of different elements always combine in one-to-one ratios.

The correct answer is B. Atoms of the same element are always identical.

Explanation:

John Dalton was an English chemist mainly known for proposing the atomic theory during the 18th century, in this theory Dalton proposed multiple laws related to the atoms, which are the smallest units of matter and they way these behave including that the mass of the elements remains constant through the chemical reactions and that each element is composed by atoms with identical features which means atoms of different elements are different and can not be changed but only combined using different ratios or proportions. Considering this, it can be concluded Dalton's atomic theory included the idea that atoms of the same element are always identical.
