how can you explain the formation of nacl according to kossel concept
Answers
Based on the kossel concept atoms need to complete their octate even they also take part in bond formation now they have to reach their nearest configuration of their nearest inert gas atoms even it can be obtained by gaining losing and sharing of electrons.
In general, a chemical bond is formed after the complete transfer of electrons from one atom to other atom even atoms acquires the nearest configuration of noble gas.
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".
