We know that the proton has a positive charge and the electron has a negative charge, and then, the neutron is devoid of any charge at all. Now, the charge on the proton and the electron are the same, but exactly the opposite.
So you can say that the amount of charge on the electron and proton are equivalent but opposite in force. Same amount of power, or charge, but opposite in reality.
The elementary charge on an electron is at 1.60217662 × 10-19 coulombs. Some say that since an electron has a negative charge, there should be a negative sign before the actual charge. The charge of protons and electrons are always the same but the charges will be different.
It will always be negative for the electron and a positive charge for the proton. The neutron is obviously neutral which means that it will not have any charge. The electron is considered to be important because it carries a lot of energy especially the electrons that can be found on the outer layer of atoms. If electrons do not exist, there are a lot of processes and items that will cease to exist.
