It has the same electron configuration as in a neon atom.
The electron configuration is [Ar]3d2.4s2.
The electron configuration of iron is [Ar]3d64s2. The electron shells contain 2, 8, 14 and 2 electrons.
The electron shell arrangement of Ceasium is 2.8.8.18.18.1
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
Electron Arrangement for Nickel: 1s22s22p63s23p63d84s2 the electron orbital arrangement in terms of increasing energy however is 1s22s22p63s23p64s23d8. Using the "noble gas core" method the arrangement can also be written [Ar]3d84s2. The arrangement for Ni2+: 1s22s22p63s23p63d8
The electron configuration of sulfur is: [Ne]3s23p4.
1s2 2s2 2p6 3s2 3p4
Sulfur must to have an electrons octet.
Chlorine has one more electron then sulfur, so it has 1 more electron in the outer shell, 1 more valence electron. Chlorine has 5 electrons in the outermost shell and sulfur has 4.
2
Oxygen is on period 2 whereas sulfur is on period 3. Therefore, sulfur has more electron shells than oxygen.
2
The electron configuration of sulfur (long) is: 1s22s22p63s23p4. The electron configuration of sulfur (short) is: [He]3s23p4.
