1870
Dalton's second theory was disproved by j.j. Thompson and ernest rutherford because dalton did not do any experiment to came out with that's theory,that is the reason why they came out with cathode ray tube and gold fuil apparatus.
theory of zonar diod
Slide Theory Stupid!!
Mutual inductance is the basic theory of the coupled circuits.
Natural Law Theory
William Crookes used a cathode ray tube to test John Dalton's theory of the existence of atoms. By observing the behavior of cathode rays in the tube, Crookes provided evidence supporting the idea of discrete, indivisible particles.
William Crookes used a device called a Crookes tube in his experiments. This was a sealed glass tube that contained rarefied gas and electrodes for producing cathode rays. The Crookes tube was instrumental in the discovery of cathode rays and contributed to the development of early atomic theory.
Sir William Crookes was a British chemist and physicist who made significant contributions to the field of atomic theory. He is best known for his work on cathode rays, which eventually led to the discovery of the electron. Crookes' experiments with cathode rays provided crucial evidence for the existence of subatomic particles and helped lay the foundation for modern atomic theory.
It is compared to William crookes

John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within
the Greek Philosophers did not test their theory.
Atoms may not be changed into other atoms.
Atoms may not be changed into other atoms.
Atoms cannot be divided into smaller particles.
Nothing,Dolton did not know about Protons,neutrons and electrons
The atom. Considered by Dalton to be indivisible and indestructible.
