n the presence of an electric field. In which two ways did this experiment change scientists’ understanding of the atom?
It showed that atoms combine in different proportions.
It showed that atoms can be divided into smaller parts.
It showed that all atoms of the same element are similar.

It showed that atoms can be divided into smaller parts.

It showed that all atoms contain electrons.

Explanation:

The experiment carried out by J.J Thomson on the gas discharge tube by passing electric current through a tube filled with many different gases provided a good insight into the structure of an atom.

This experiment led to the development of the plum pudding model of the atom.

Cathode rays and it properties were discovered in this set up.
It furnished the scientific community with evidences that atoms can be divided into smaller parts.
Since atoms now contain some subatomic particles, they can be broken down in like manner into further bits.
The cathode rays which were later termed electrons became a fundamental particles known for every atom.
