Question

write the formation of nacl
​

Answer 1

                               Formation of NaCl:

1. Sodium has atomic number 11, shows the electronic configuration 2,8,1 to become complete by it's octet state, Sodium looses it's 1 electron and forms the sodium ion Na+ (2,8).

Sodium (Na) (2,8,1)  -------------> Sodium ion (Na+) (2,8)

2. Chlorine has atomic number 17, shows electronic configuration 2,8,7. To become complete by it's octet state, it accepts 1 electron shared by Sodium and forms the Chlorine ion Cl- (2,8,8)

Chlorine (Cl) (2,8,7) --------------> Chloride ion (Cl-) (2,8,8)

3. Due to the opposite charges, there is a attraction between this two ions and one new chemical bond is formed.

                           Na₊ + Cl₋ -------------> NaCl

About Sodium Chloride:

Sodium Chloride is a common salt which is generally referred as "common salt" also. Sodium Chloride is colorless and crystalline ionic compound. By the further reactions on Sodium Chloride, Various salts like Na2Co3 and NaHCO3 are produced.

i) NaCl is generally salty in taste.

ii) It is Colourless , Neutral salt.

iii) There is no water of crystallization in it's crystalline structure.

iv) When the NaCl is heated at 800 degree Celsius, then it melts. This state of salt is called as "Fused state of salt".

Answer 2

SA Answer Explanation:

• In Nacl there are two atoms, they are Sodium (Na) and Chlorine (Cl).
• Every Atom tries to get the Inert Gas configuration to become Stable.
• Sodium(Z = 11) it's Electronic Configuration is $1s2, 2s2, 2p6, 3s1$.
• The nearest Inert Gas is Neon [Ne]. For Sodium (Na) atom to get the nearest Inert Gas Configuration is to lose 1 electron{e-}  and become Na+ ion.
• The other Atom is Chlorine(Cl) (Z = 17) it's Electronic Configuration is $1s2, 2s2, 2p6, 3s2, 2p5$.
• To get Inert Gas configuration Chlorine(Cl) needs One electron, the nearest Inert Gas is Argon[Ar].
• Sodium(Na) is highly Electro positive element which is ready to donate the electrons{e-}, whereas Chlorine(Cl) which is higly electro negative element which helps to ready to take the electrons{e-}.
• Tosatisfy the Inert Gas Configuration (Octet Configuration) Sodium (Na) is ready to donate the electrons to Chlorine(Cl) and then Chlorine accepts tthe electrons{e-}.
• Hence, there is a transfer of electrons from 1 Ion to another Ion, And the bond form is called as "Ionic Bond".
