Sodium chloride = NaCl
Na : atomic no. 11
electronic configuration :
K L M. : Na 1+
2 8 1
Chlorine = Cl atomic no. 17
electronic configuration
K L M. Cl 1-
2 8 7
Cl ( 7 electrons in outer shell). Na ( 1 electron in outer shell)
Cl needs 1 electron to complete it's octate so Na gives Cl one electron by which Na also have a complete octate and Cl also
Forming NaCl.
Melting point of NaCl is high because it is a ionic bond and have strong intermolecular force of attraction.
