Question

write the electronic configuration of sodium and chlorine show the formation of sodium chloride by the transfer of electrons and what type of compound is this
​

Answer 1

Answer:

Electronic Configuration of

SODIUM- 2,8,1

CHLORINE-2,8,7

Sodium chloride compound is formed when sodium donates a electron from it's outer shell,and chlorine accepts that electron to form compound called sodium chloride.Both donates and accept electron to become stable.

Electronic Configuration after formation of compound

SODIUM -2,8

CHLORINE-2,8,8

The compound formed is an electrovalent coumpound

"The elements must have 8 electrons in their valence shell to become stable".

plz mark me as brainliest.

Answer 2

Answer:-

Sodium - Z = 11 ; Symbol - Na

Electronic configuration: 1s² 2s² 2p⁶ 3s¹

Chlorine - Z = 17 ; Symbol - Cl

Electronic configuration : 1s² 2s² 2p⁶ 3s² 3p⁵

In the reaction of Sodium chloride (NaCl) , 1 electron is transferred from Sodium to Chlorine.

As we know, the complete transfer of 1 or more electrons from one atom to another is called an Ionic Compound.

Hence, we can say that Sodium chloride is an Ionic Compound.

Additional Information:

Electrovalent or Ionic Bond:

• The chemical bond formed between two or more atoms as a result of the complete transfer of 1 or more electrons from one atom to another is called Ionic or Electrovalent bond.

• Electro positive atom loses electron (Group - IA to III A) and Electronegative atom gains electron (Group - VA to VII A).

• Electrostatic force of attraction between cation and anion is called Ionic Bond.

• IA and VII A group elements form Maximum Ionic Compound.
