I am Proton
We know the story of Electron. Now we come to its opposite i.e. Proton. How we found it and know more about it.
When the electron was discovered and it was also discovered that there is a negative charge on the electron. And at the same time we also knew that the atom is a modified particle. So now there were two types of possibilities. One is that if the atom is a modified particle and the electron that is present in the atom has a negative charge, then for adjustment it is necessary that there should be another particle in the atom that has a positive charge, that cancels the negative charge of the electron. The second is that the presence of a negative charge on an electron is a lie. Now, to declare one of these two as correct, various scientists started struggling. Among them, E Goldstein set up an experiment in 1886. The experimental setup of this experiment was exactly like a cathode ridge except that the porous cathode was used here and secondly, the pressure was 0.001atm
Experiment
Goldstein maintained the pressure described above when experimenting and carried the voltage to 10000 volts.
Observation
In the condition described above, he found that apart from the cathode ridge, another set of rays was moving from the anode to the cathode and passed over the pores to produce fluorescence on the fluorescent screen attached behind the anode. At that time, he thought that these rays emanate from the anode like cathode rays, so he named it an anode ray. Similarly, because these rays pass through the pores, they are also called Canal Rays.
Where do Canal Rays come from?
When asked this question, the answer immediately comes to our mind that if the cathode rays emit from cathode, in the same way, Canal Rays emit from anode. However, Canal rays are actually ions produced by the gas that is inside the discharge tube. The argument that is made about this is that when we find out the value of Canal Rays by e/m formula, it varies for different gases and the highest value is when the gas in the discharge tube is hydrogen. This proves that hydrogen is the lowest mass factor.
Charge to Mass (e/m) ratio
As it was known for electrons, it also found a charge-to-mass ratio for protons. And the most that was for hydrogen was
9.87×10⁷C/Kg
Charge
The charge that was detected on the protons was done by a very similar experiment that Milliken did for the electron, simply inverting the order of the positive and negative plates. And it was found that the charge on it is also equal to the electron, but it is positive.
Mass
Now we know the above two things experimentally, so we can find out the mass from the calculation
e/m = 9.87×10⁷ C/Kg
e = 1.602 ×10-¹⁹C
Mass = 1.6726 × 10-²⁷Kg
Now I am going to leave an important question for you guys here. "How is it known that hydrogen has only one electron and one proton?"
