As we know that the charge of the electron is equivalent to the magnitude of the elementary charge that is (e) but bearing a negative sign.
Since, the value of the elementary charge is roughly
[tex]1.602 \: \times \: {10}^{ - 19} C[/tex]
then, the charge of the electron is :
[tex] - 1.602 \: \times \: {10}^{ - 19} C[/tex]
Here, C is the unit of charge is Coulomb.
So, the charge on an electron is (-1).
