Question

What was Thomson’s conclusion from cathode ray tube experiments?

Answer 1

Hint: We need to know that the cathode ray tube experiment of an atom is conducted by J.J Thomson and he shows the electrons are encircling by a volume of positive charge and negatively charged. The plum pudding model of the atom is put forward on \[1904\]. By using this model, scientist Ernest Rutherford performed the gold foil experiment. According to this experiment, he concluded that the atom does not contain any space and it has a positively charged nucleus.

Complete answer:
We have to remember that the scientist J.J Thomson proposed the cathode ray tube experiment on \[1904\]. He discovered the electrons are encircling by a volume of positive charge and negatively charged. Here, the negatively charged part is considered “plum” which is electrons and the positively charged species is considered pudding. Hence, that experiment is called plum pudding model. And he concluded from the cathode ray tube experiment that the atom can be divided into smaller particles. And every atom has a negatively charged particles which is smaller than the atom and that particle is known as electrons. And these are the fundamental charged particle which is present in the atom.

Note:
We must know that the plum pudding model of atoms was discovered by the scientist J.J Thomson in the nineteenth century. In that experiment, he showed an atom with positive and negative charged species in the model and he called that experiment, “plum pudding model of atom”. Because, that structure has a resemblance with the structure of an atom and it gives an idea about the spherical shaped structure of an atom.
