WebJul 4, 2024 · How many electrons are in a chlorine anion Cl −? 2: The Formation of a Chlorine Ion. On the left, the chlorine atom has 17 electrons. On the right, the chloride ion has 18 electrons and has a 1− charge. With two oppositely charged ions, there is an electrostatic attraction between them because opposite charges attract. WebFor instance, the ground state electronic configuration of calcium (Z=20) is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2. The calcium ion (Ca 2+ ), however, has two electrons less. Hence, the electron configuration for Ca 2+ is 1s 2 2s 2 2p 6 3s 2 3p 6. Since we need to take away two electrons, we first remove electrons from the outermost shell (n=4).
