Question

2. J.J. Thomson's cathode-ray tube experiment showed which of the following? Electrons are in a cloud surrounding positively charged particles.

Atoms consist of at least some negatively charged particles.
Matter can be neither created nor destroyed.
Atoms are small individual spheres.

Answer 1

Atoms consist of at least some negatively charged particles.

This experiment allowed for the "plum-pudding" model to be advanced by Rutherford.

Answer 2

The correct answer will be option atoms consist of at least some negatively charged particles.

Step-by-step explanation:

J.J Thomson is known for his discovery of a negatively charged sub-atomic particle called electrons in 1897.

He discovered that when the gas sample is filled between two opposite charged plates, the atom of gas got ionized due to the rays containing charged particles coming from the cathode and found them to be negatively charged which got deflected in a magnetic field and named them electrons.

Thus, selected option is the correct answer.
