A proton is a subatomic particular, which has a positive electric charge. It has a +1e elementary charge, which has an equal charge in magnitude toanother electron.
Proton has a lesser mass than the neutron. Neutron and proton, together with one atomic mass unit, are collectively called the “nucleons”.
Protons, along with the neutral particles, constitute the atomic nuclei for the hydrogen nucleus.
It is so because the hydrogen nucleus consists of a single proton.
Every nucleus of the chemical element has an equal number of protons in it. The numbers define the atomic number of an element.
The proton numbers are also said to determine the position of a particular element on the periodic table.
But when the proton numbers in a nucleus are equivalent to the number of neutrons in a nucleus, it is called a neutral chemical element.
The discovery of the proton in the atomic structure dates back to the atomic structure investigations.
Ernest Rutherford was the person who had discovered the Proton almost 100 years ago.
In his publications, he proved the existence of the proton in his findings.
Main Features of the Proton
Following are the main features of the protons:
- Protons are the subatomic particle that has a positive charge of 602 × 10−19C. The same information data can also be written in the “+1”.
- The protons are the positively charged particle that has a mass of 673 × 10−27kg (938.27 MeV/c2).
- When we compare the protons to the electrons, protons have the 1837 times heavier than the electrons. Electrons are not as heavy as protons. Protons are the heaviest subatomic particles.
- Protons are also called Nucleons. There are also other subatomic particles which are neutrons and electrons. From these particles, it is the neutrons that are called nucleons. Protons and neutrons are the nucleons, as these two are the elementary particles of the nucleus.
What is the Electron?
Electrons are the negatively charged particles of a nucleus of an atom.
Together, the electrons have a negative charge, which balances the positive charge of the protons in the nucleus of an atom.
The total mass of an electron is 1000 times smaller than the total mass of a positively charged proton.
Electrons are the fundamental part of the nucleus of an atom, which does not consist of anything smaller.
Joseph John Thomson (J.J. Thomson) had discovered the electron. He is a Cavendish Professor of Experimental Physics at the University of Cambridge. J.J.
Thomson was the director of the Cavendish Laboratory from the year 1884 to the year 1919.
Main Features of the Electron
Following are the main features of the Electron subatomic particle:
- Electrons are a subatomic particle that has a negative charge.
- The electrons move around the atom’s center, called the nucleus, at different energy levels.
- If electrons absorb the energy, scientists can undertake experiments to excite their energy to higher levels.
- The mass of the electrons is 1/2000 times that of the neutron and the proton.
What Was The Potential Difference That Stopped The Proton?
We will solve this problem in three different parts. These parts are given below:
Proton goes into a higher potential region because it should get in the opposite direction for getting rest.
The potential difference between the kinetic energy of the proton is calculated hereunder:
ΔV = mv2 / 2q (express the v)
ΔV = mv2 / 2c (replaces the charge of a proton)
ΔV = 1.67 . 10 – 27 .8000002 / 2. 1. 602. 10 – 19(Substitute)
Part ( c )
We will get the initial kinetic energy of the proton in case we substitute the data for the definition of the kinetic energy.
ΔK = mv2 / 2
ΔK = 1.67 . 10 – 27 . 8000002 / 2 (Substitute)
ΔK = 5.34 . 10 – 16 J
ΔK = 5.34 . 10 – 16 J / 1. 602 . 10 – 19 J
Result of the Problem
Solution of the Part (b) = ΔV = 3335.8V
Solutionof the Part ( c ) = 3335.8eV
What Was The Potential Difference That Stopped The Electron?
We will answer this question in three parts, which are A, B, and C.
Each part will define and detail the factors that will calculate the potential difference that had stopped the electron.
The electron goes into the region of potential that is lower. It t is so because it has to go in the opposite direction of force for experiencing the rest.
We will calculate the potential difference that had stopped the electric by defining the kinetic energy. It is the following:
ΔV = mv2/2q (Expresses ΔV)
ΔV = mv2/2c (Substitute Charge of an Electron)
ΔV = 0. 11. 10 –31 .5000002 / 2. 1.602. 10 – 19 (Substitute)
Part( C )
The initial kinetic energy os the electric we attain if replace the data in the explanation of the kinetic energy:
ΔK = mv2/ 2
ΔK = 9. 11. 10 – 31 . 5000002 / 2 J (Substitute)
ΔK = 1. 139. 10 – 19 / 1. 602. 10 – 19 J
Result of the Calculations
In the above calculations, we had established the following results:
Part (a) : Electron goes into the lower potential region because it goes into the opposite direction for experiencing the rest.
Part (b): ΔV =
Part ( c ) =
Did The Electron Move Into A Region Of Higher Potential Or Lower Potential?
An electron is a subatomic particle that has a negative charge. Electron subatomic particle exerts a negative charge.
So, the electron negative charge will go in the opposite direction for the direction of the electric field.
So, the electrons go from the lower potential regions into a higher potential region as it has a negative charge.
