In the periodic chart, the mercury atomic number is 80 and it is symbol Hg
Large atoms require low energy for ionization, however, small elements require high energy for ionization.
A diode filled with gas is called a phantom (or thyratron).
A filament that is put under the cathode plate glows and provides the thermal heat to the Cathode.
At a certain amount of kinetic energy of the emitted electrons, reaches that level where they are able to knockout the electrons from mercury atoms.
Space charge region, i.e., the negatively charged region containing the electron cloud due to the accumulation of electrons emitted by the cathode
#Q. WHAT IS FIRST IONIZATION ENERGY? First ionization energy is that energy which is required to remove the first electron from the atom
