why the electronic configuration of calcium is 2 8 8 2 …

2014/1/3· Calcium has 20 electrons and m shell is a 3rd energy level. Its electronic configuration is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 instead of 1s 2 2s 2 2p 6 3s 2 3p 6 3d 1 4s 1 . This is because of Afbau’s principle which states that electrons fill orbitals starting at the lowest available (possible) energy levels before filling higher levels (e.g. 1s before 2s and 4s before 3d ).

Electron Configuration for Iron (Fe, Fe2+, and Fe3+)

In writing the electron configuration for Iron the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Iron go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons.
