Yes and no. Technically speaking the charge of a subatomic particle such as an electron or proton is always the same, this is why they are called constants. However, the methods that have been employed to determine the actual value of the elementary charge may not be the correct value. This would be due to experimental error, etc.
Electron carries negative charge. Electron is an elementary particle.
The positive elementary electric charge is called a proton.
The Proton has a positive charge equal to the elementary charge. This is due to its composition of a down quark and two up quarks which have charges of -1/3 the elementary charge and +2/3 the elementary charge respectively.
The electric charge of a proton is +1 elementary charge unit. That means its charge is 1.6021764e-19 Coulombs.
The charge of a muon is -1 elementary charge, which is the same as the charge of an electron.
The elementary charge is the fundamental unit of electric charge in physics, denoted by the symbol "e." It has a value of approximately (1.602 \times 10^{-19}) coulombs and is the charge carried by a single proton, while an electron carries a charge of (-e). This charge is considered the smallest indivisible unit of charge in nature, and all electric charges are integer multiples of the elementary charge.
A proton has a positive charge of +1 An electron has a negative charge of -1 An neutron has no charge
charge
The electric charge of a muon is -1 elementary charge, which is the same as the charge of an electron.
Elementary charge is the charge of a proton or an electron. It is denoted by the symbol "e". Its value is 1.602 x 10-19 C
1.602e-19 is the value in coulombs of the "Elementary charge", denoted by e.
An elementary particle carrying a unit charge of negative electricity is called an electron.
