Electron Configuration Of Sodium Ion. For example, a sodium atom, na, has a single electron in its valence shell, surrounding 2 stable, filled inner shells of 2 and 8 electrons. For example, the electron configuration of sodium is 1s 2 2s 2 2p 6 3s 1.
To save room, the configurations are in noble gas shorthand. Thus, you should write the electron configuration for 10 electrons. The electron configurations of sodium and chloride ions—the components of table salt (nacl)—provide a useful insight to the octet rule.
Since, in a neutral molecule, the number of protons is equal to the number of electrons, we can also deduce that sodium also has eleven electrons.
What is the most likely electron configuration for a sodium ion in its ground state? Therefore the iron electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 6. The total number of electrons is 11 in the sodium atom. Thus, sodium ion (na+) has.
