One of the things that Dalton believed was that the atoms of an element were identical to each other. Something evident to you, but was revolutionary at the time. Now we understand why this is the case and can include the number of protons in the definition of an element as follows - atoms that have the same amount of protons are the same element. Can you ace this Atomic Structure quiz?
