Question
Which statement accurately reflects a key postulate of John Dalton's atomic model?
Correct Answer
Option B is the correct answer.
Detailed Explanation
John Dalton suggested that 'atoms of the same element are same: specific elements have only one type of atom in them, each atom has its own constant mass that varies from element to element.' Options A and D contradict later models, and option C contradicts Dalton's postulate that 'atoms can neither be created nor destroyed but can be transformed from one form to another.'
Hint
Recall Dalton's fundamental ideas about atoms, especially regarding their nature within an element.
