Question

Wat s the electronic configuration of sodium and chroline to show the formation of sodium chloride

Answer 1

Answer:  NaCl is an ionic compound.

In the formation of NaCl is by the combination of Na+ (cation) and Cl- (anion)

Na will lose one electron and become cation

ie, Na+ (electronic configuration 1s2 2s2 2p6)

and Chlorine receive one electron and becomes anion

ie, Cl-   (electronic configuration 1s2 2s2 2p6 3s2 3p6)

Explanation:

The atomic number of Sodium is 11

ie, the electronic configuration of Na is 1s2 2s2 2p6 3s1

The atomic number of Chlorine is 17

ie, the electronic configuration of Cl is 1s2 2s2 2p6 3s2 3p5

the outer subshell electrons are participated in the reaction.

ie, Na- [Ne] 3s1 and Cl [Ne] 3s2 3p5
