Full question:

Which of these discoveries contradict components of Dalton's atomic theory? Check all of the boxes that apply.

A. Atoms contain smaller particles: protons, neutrons, and electrons.

B. Atoms of a given element can bond to other atoms only in specific ways.

C. Atoms of a given element can have different numbers of neutrons.

D. Nuclear reactions can change an atom of one element into an atom of another element.

E. All atoms of a given element have the same number of protons.

Answer:

Atoms contain smaller particles: protons, neutrons, and electrons. Atoms of a given element can have different numbers of neutrons. Nuclear reactions can change an atom of one element into an atom of another element.

Explanation:

Atomic theory by Dalton suggested that every object was comprised of atoms that are unbreakable and unchangeable structure segments. The indivisibility of an atom was fixed incorrect: an atom can be additionally partitioned into protons, neutrons, and electrons.

According to Dalton, the atoms of the alike element are related in all esteem. Still, atoms of unusual elements differ in their volumes and quantities. Dalton also proposed that chemical reactions occurred in the rearrangement of the reacting atoms.
