Question

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. Which other model or scientific observation would have also been supported?

This would support Dalton's postulates that proposed the atoms are indivisible because no small particles are involved.
This would support Bohr's prediction about electrons moving in orbits having specific energy.
This would support Bohr's prediction about electrons being randomly scattered around the nucleus in the atom.
This would support Dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.

Answer 1

Answer:

This would support Dalton's postulates that proposed the atoms are indivisible because no small particles are involved.

Explanation:

Experiment using the gas discharge tube by J.J Thomson led to the discovery of cathode rays which are now known as electrons.

Primarily, Thomson's experiment led to the discovery of cathode rays, electrons, as subatomic particles.

If the size of the atoms observed at the cathode is the same as that of the rays,we can conclude that the particles of the rays are the simplest form of matter we can have. This would suggest that the atom is indeed the smallest indivisible particle of a matter according to Dalton.

Answer 2

Answer:

This would support Dalton's postulates that proposed the atoms are indivisible because no small particles are involved.

Explanation:

Dalton proposed that all matter is made up of atoms. Atoms are indivisible. But Thompson’s cathode ray experiment proved that the cathode rays are made up of negatively charged particles which were deflected by both electric and magnetic field. This caused Thompson to propose the Plum and Pudding model of the atom.
