Electron configuration of sodium and Sodium ion

Sodium is denoted by the letter Na and its atomic number is 11. The number of electrons in Sodium is 11. This post we will checking Electron configuration of sodium and Electron configuration of sodium ion

Electron configuration of Sodium

Electron configuration is the Arrangement of electrons in different orbitals of an atom. The electronic configuration of sodium is given by

1s² , 2s², 2p⁶ ,3s¹

or

2, 8,1

we can write the electron configuration in the orbital diagram as below

Sometimes, we can write the electron configuration in short form as

[Ne] 3s¹

Where [Ne] stands for electron configuration of Neon i.e 1s² , 2s², 2p⁶ 

Electron configuration of Sodium ion

• The sodium ion is formed by losing 1 electron. The number of electrons in Sodium Ion is 10
• The electronic configuration of Sodium Ion is given by

1s² , 2s², 2p⁶ 

we can write the electron configuration in the orbital diagram as below
