WebAluminum Cation Al+3 CID 104727 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety ... 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).
