WebThe charge of electrons is –1.609 × 10 –19 coulombs and the relative charge is –1. That is, the charge of an electron is equal to that of a proton but the opposite. We must also remember that the number of protons and electrons in an element is equal. Therefore, an astatine atom contains eighty-five electrons in its orbits.
