thonmson discovered that the atom contained smaller particles called electrons
Thomson's experiment showed that atoms contain subatomic particles, specifically electrons. This discovery led to the modification of Dalton's atomic model, which previously considered atoms to be indivisible and uniform. Thomson's model proposed the existence of electrons within the atom.
If all four postulates of Dalton's atomic theory were correct, the boxes on the periodic table would not change. Dalton's theory helped establish the concept of elements as composed of atoms, leading to the organization of elements on the periodic table based on their atomic number and properties. The periodic table would still be structured according to the number of protons in the nucleus of each element's atom.
You can change the independent variable in an experiment, which is the factor you manipulate to see its effect on the dependent variable. This change allows you to observe how different conditions impact the outcome of the experiment.
You add an independent variable to an experiment to make a change. This variable is manipulated by the researcher to see if it has an effect on the outcome of the experiment.
No, the atomic number remains the same when an ion is formed. The atomic number is determined by the number of protons in an atom, which does not change when an atom becomes an ion by gaining or losing electrons.

Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were in.

An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.

Variables that do not change in an experiment are independent variables.
