What are 3 properties of an ionic bond

Compound with ionic bond having high melting and boiling  point.

They conduct electricity.

In solid form do not conduct electricity.

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Properties:

Compound with ionic bond having high melting and boiling  point.

They conduct electricity.

In solid form do not conduct electricity.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
