Electrons do have charge. The chare of an electron - 1.602*10-19 C
electrons with a charge of -1.6*10^-19 Coulomb.

The Coulomb is a 'derived' unit depending on the basic units of the metric system. So one Coulomb is the amount of charge in an electric current of one Ampere/second--the Ampere being the current required to obtain an amount of magnetic force between a pair of current carrying wires. The Millikan oil drop experiment, which measures the charge on a single electron, provides the answer to how many electrons per second are in one Ampere. A single electron has a charge of 1.60217733 × 10-19 Coulombs. A collection of 6.2415 × 1018 electrons has a charge of one Coulomb (1/1.60217733x10-19).

Charge on electron = - 1.602 X 10 -19 coulomb, so..., - 58. 0 coulomb/- 1.602 X 10 -19 coulomb = 3.62 X 1020 electrons ===============
Electrons do have charge. The chare of an electron - 1.602*10-19 C
A coulomb is a measure of electric charge and is equal to -6.24151 x 10^18 electrons.
Charge ofprotons is +1 (e.c.q. = 1.602*10-19 Coulomb)electrons is -1 (e.c.q. = 1.602*10-19 Coulomb)neutrons is zero, neutral

coulombs 1 coulomb is equal to the charge of 6.24 x 10^18 electrons
The elementary charge ... the amount on one electron or one proton ... is 1.602 x 10-19 coulomb.So, in order to collect one coulomb, you'd need 6.242 x 1018 electrons or protons.(That's the number of electrons that pass by the middle of the wire every secondwhen the current in it is 1 Ampere.)
