Describe how sodium and chlorine form sodium chloride. Name the type of bonding shown in the structure (At no. : Na=11, Cl=17)
OR
Show the formation of Nacl with the help of electron dot structure.

Text Solution

Verified by Experts


Chlorine, atomic number 17(17 electrons)
electronic configuration 2,8,7
valency: 1
Chlorine atom gains one electrons in its last shell and forms a monovalent negative ion.
`underset(2,8,7)(Cl)+le^(-)tounderset(2,8,8)(Cl^(-))`
The sodium and chlorine ions get attracted by strong electrostatic forces of attraction and form the ionic compound NaCl (Sodium chloride)
The type of bond formed in the structure is ionic.
