The two ways the cathode ray tube experiment changed scientists'

understanding of the atom was it showing that atoms can be divided into

smaller parts and all atoms contain electrons.

J.J Thompson was the scientist which performed the cathode ray tube

experiment and was able to ascertain it was negatively charged as a result

of it being deflected to the positive electrode.

His observation showed that the atoms contain sub-atomic particles called

electrons which are negatively charged.
