JJ Thompson passed an electric current through a gas at low pressure from the negative terminal to the positive terminal then decided that the ration is always the same regardless the gas used.
How would the electrons produced in a cathode-ray tube filled with neon gas compare with the electrons produced in a cathode-ray tube filled with chlorine gas?
Chlorine is smaller in size as compare to Bromine so its electronegativity or electrons attracting ability is higher which is responsible for the loss of electrons from other atoms hence it is strong oxidizing agent.
Compare the electronegativity of calcium to the electronegativity of chlorine. Find the number of electrons each will give up / accept. Balance the two. Calcium easily gives up two electrons. Chlorine easily accepts one electron.
Bromine's atomic radii is larger than that of chlorine.
In most cases, chlorine is more reactive than bromine. This occurs because chlorine has a higher electronegativity than bromine. Thus, chlorine tends to take electrons from other substances more readily than bromine, and thus is more reactive.
Salt is a common condiment, while sodium burns on contact with water and chlorine gas is poisonous.
the results are the same regardless of the gas

the plane of polarization matches the vibrational direction of the electrons
The Anode (+) is what you connect the positive voltage to The Cathode (-) is what you connect the negative voltage to.

Valves, or vacuum tubes, were large, generated tremendous heat, and were prone to failure.Vacuum tubes worked much like transistors, but required a filament to heat the cathode so that electrons could flow through the plate when there were the proper grid voltages for that. If the cathode heater burned out, the cathode would not work, and the tube would need to be replaced. Comparing to a PNP or NPN transistor, the cathode would be equivalent to the emitter, the plate would compare to the base, and the grid would computer to the collector. Comparing to an FET, the cathode would be the source, the grid would compare the the gate, and the plate would compare to the drain.
Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
