Formation of sodium ion from sodium atom

In this article, we will learn about the formation of sodium ions from sodium atoms.

 Formation  of sodium ion from sodium atom 

We know an atom is a neutral particle that has an equal number of protons and electrons.

Each atom wants  8 electrons in the outermost shell to become stable.

Electronic configuration of sodium

Sodium atom has 11 protons in the nucleus and 11 electrons in different orbitals.

`1s^2 2s^2 2p^6 3s^1`

There is one valence electron present in the outermost shell of the sodium atom.

Formation of sodium ion

Sodium donates or loses 1 electron from its outermost shell or valence shell.

After losing 1 electron, sodium achieves noble gas [Ne] electronic configuration.

`1s^2 2s^2 2p^6`

Now . sodium has 11 protons and 10 electrons.

Protons are positively charged sub-particles, so sodium has one positive charge and becomes a sodium cation[`Na^+`]
