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). WebTo find the electron configuration for an ion, first identify the configuration for the neutral atom. Then, add or remove electrons depending on the ion's charge. For example, to …
WebAt your level it's enough to know that metals generally form positive ions and non-metals form negative ions. The size of the charge is equal to the number of electrons needed to get to the "closest" 8 (or two in the case of period 2 metallic elements). So Aluminium is 2,8,3. It could go to 2,8,8 or 2,8. The latter is "closer" (lose three vs ... WebApr 5, 2024 · The total number of electrons in the molecules or ions is equal to the sum of the electrons in the atoms in the molecules or ions.
