Question

Write the electron - dot structure for Na and Cl atoms. How do these form a chemical bond? Name the types of bond so formed. Why does a compound so formed have high melting point.

Answer 1

Explanation:

Na: in K shell 2electorn, L shell 8 electron, M shell 1 electron. so it's valency is '1' means to leave one electron.

AND

Cl: in K shell 2 electron, L shell 8 electron, M shell 7 electron. so it's valency is '1' means to consume one electron.

These form a chemical by electrolysis.

The name of this type of bond is ionic bond.
