Four imporfant properties of cathode rays

The figure showing discharge tube experiment with perforated cathode is shown below: Mention any two properties of each rays.

Write any two characterisitcs properties of canal rays.

Transition elements are d- block elements Write any four characteristic properties of transition elements.

Assertion : The characteristics of cathode rays do not depend upon the material of electrodes and the nature of the gas present in the cathode ray tube. Reason : Cathode rays consist of negatively charged particles, called electrons.

Thomson performed his famous “cathode ray tube” experiment, and came to the conclusion that

Consider the following statements, which of the following is/are true? i) Charge to mass ratio of canal rays are found to depend on the gas from which these originate ii) Cathode rays produce fluorescence and phosphorescence when it hit on the corresponding materials iii) J.J. Thomson's model of an atom could clearly explain "atom is electrically neutral" iv) Behaviour of canal rays in the electrical or magnetic field is opposite to that observed for cathode rays v) Charge to mass ratio of cathode rays are found to depend on the gas from which these originate
