Question

02.01]In the 1800s, John Dalton's atomic theory was that atoms are indivisible. Later, subatomic particles such as neutrons, electrons, and protons were discovered. What happened to the indivisible part of Dalton's atomic theory, and why? The theory remained unchanged because Dalton was correct regarding all other statements within the accepted scientific theory. Dalton's theory remained intact, and the new evidence was ultimately discarded because new data must fit within the current accepted theory. The indivisible part of the theory was voted upon by the scientific community because validity is based on the majority of scientific opinions. The indivisible part of the theory was discarded after the subatomic particles discovery because consensus of data must exist for theories to be valid.

Answer 1

The last one is the correct answer. The atomic structure can be broken down which is what the findings concerning protons, electrons and neutrons showed. The theory was thus modified. What remained was no chemical reaction could affect the basic structure of an atom.

Still the last choice is still true. The first choice is your second best answer because of what I wrote in the last sentence of the above paragraph.

Answer 2

Answer:

The correct answer will be option- The indivisible part of the theory was discarded after the subatomic particles discovery because consensus of data must exist for theories to be valid.

Explanation:

John Dalton is known for his atomic theory which states that matter is made up of indivisible atoms.  

The subatomic particles of the atom were first discovered by J.J Thomson in 1897 when he discovered electrons, In 1920 Rutherford discovered protons and in 1932 James Chadwick discovered neutrons.

This led to a shift in the paradigm that atom is indestructible as new discoveries led to changes in the consensus data which opposed the atomic theory. This discarded the indivisible atomic theory.

Thus, the selected option is the correct answer.
