dalton stated that all atoms of a given element are identical. is this true or false?

Answer 1

False

Isotopes are still considered the same element by most.
These differ in that they contain more neutrons in the nucleus.

another reason:
An atom in a compound is different than an atom of the same element in a different compound in its electon arrangement.

Answer 2

To give this full merit Dalton stated that atoms of a given element are identical both in mass and in chemical properties. This is FALSE because as we know isotopes of elements are not identical in these properties.

Answer 3

Of course not. He was close, though. All Dalton knew was the average mass of an atom, since mass spectrographs were not available in the first decade of the 19th c. Once we were able to sort out the different isotopes of many elements, we realized that what we saw as the atomic mass of an element was really a weighted average of all the isotopes of that element. Isotopes differ by mass, not chemical properties, so Dalton could not differentiate them by chemical means.

Answer 4

i am pretty sure it is true, because atoms = atoms. the only difference you can have with atoms is if they ionize with another element, but then they are no longer atoms anyway. if they gain mass, then they are not identical, but are the isotopes of each other. so in theory, dalton was correct.
