Sodium in all its compounds forms the Na+ ion.
Its electron configuration is the same as of noble gas Ne:
(Na+) = (1s2, 2s2 2p6, 3s0)
Na2+ would have the following electron configuration: 1s2, 2s2 2p5
This is not a noble gas configuration and requires a lot of energy to remove the 2nd electron out off the 2px orbital just after the 1st removal from its 3s orbital. It only is observed for example as a transient species when sodium vapour is irradiated with strong laser light.
Sodium's atomic number is 11. Therefore, were it electrically neutral, sodium would have 11 protons and 11 electrons. However, Na+ has one less electron. So, filling in the first 10 electron orbitals gives an electron configuration of 1s2 2s2 2p6.
Na+ has an electron configuration of 1s22s2 2p6
The electron configuration of sodium is [Ne]3s1.
1s2 2s2 2p6 3s1 OR [Ne] 3s1
1s2 2s2 2p6 3s1
1s2 2s2 2p6 3s1
1s^(2)2s^(2)2p^(6)
1s22s23p6
[Ne] 3s1
Let us assume that we have Sodium (Na), it has the ground state electron configuration of: [Ne]3S1. The ANION is negative, and thereby has more electrons, the Na anion(Na.) would have the following electron configuration: [Ne]3S2. The CATION(which is a positive ion) of Na(Na+) would have [Ne] as it electron configuration(as it loses an electron and becomes "equal" to Neon)
The Fe2 plus electron configuration is 1s2 2s2 2p6 3s2 3p6 3d6.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
N3- , O2- , F- , Na+ , Mg2+ , Al3+ all have the same electron configuration as Neon.
The electron configuration of sodium is: [Ne]3s1.
