Based on experimental evidence, John Dalton postulated that ________.
A)each element consists of indivisible, minute particles called atoms
B)atoms can be created and destroyed in chemical reactions
C)not all atoms of a given element are identical
D)atoms of different elements have the same masses

Question

Quizplus · Accepted Answer

John Dalton's postulation of atoms as indivisible, minute particles is the basis for modern atomic theory. He believed that each element was made up of a unique type of atom that could not be created or destroyed in a chemical reaction. Dalton did not propose that atoms could be created or destroyed, which eliminates choice B. He also observed that atoms of different elements have different masses, meaning option D is incorrect. Finally, Dalton's postulation that each element's atoms were unique and indivisible disproves option C.
