2 Atoms of same element have same mass"- this statement of Dalton was proved wrong after the discovery
of-
(A) isotope
(B) isobar
(C) isotone
(D) isomer​

Answer 1

Answer:

What have we learned since Dalton proposed his theory? The short answer: a lot! For instance, we now know that atoms are not indivisible—as stated in part one—because they are made up of protons, neutrons, and electrons. The modern picture of an atom is very different from Dalton's "solid, massy" particle.

Explanation:

The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects
