Electron Configuration Of Sodium Ion
Therefore the electron configuration of the sodium ion is 1s 2 2s 2 2p 6.
Electron configuration of sodium ion. Sodium which symbolized as na is a group 1 element with the atomic number 11. Its electron configuration is 1s 2 2s 2 2p 6 3s 1. In this video we will write the electron configuration for na the sodium ion. Thus sodium ion na has eight valence electrons.
Sodium has properties of a group 1 metal. In the case of sodium the one lone electron in the 3s valence shell would easily be released in order for sodium to have a filled valence shell at 2 s2 2 p6. The electron configuration of neutral na is 1s22s22p63s1 but in na it loses one electron so it has a new electron configuration of 1s22s22p6 means na has 2 6 8 outermost electrons which makes it stable. The sodium ion na has the electron configuration with an octet of electrons from the second principal energy level.
It is now the same as that of the noble gas neon. Therefore the electron configuration of the sodium ion is 1 s2 2 s2 2 p6. No follow up the electron configuration of the ion is the electron configuration of the neutral atom minus the number of electrons lost to form the positive ion. Because sodium gives up the electron from the 3s orbital it now has only 10 electrons but still has 11 protons giving it a 1 charge and it becomes a na cation.
Na ne 3s1. Sodium is the first element in the third period so the electrons have started to fill into orbital 3. The term isoelectronic refers to an atom and an ion of a different atom or two different ions that have the same electron configuration.
