WebHow many protons, neutrons, and electrons are in atoms of these isotopes? Write the complete electron configuration for each isotope. Answer. Co has 27 protons, 27 electrons, and 33 neutrons: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 7. I has 53 protons, 53 electrons, and 78 neutrons: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 10 5s 2 5p 5. 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.
