INTRODUCTION :

1.What is the difference between ionic and covalent bonding

IONIC BONDING: It is an electrostatic bonding.The electrostatic attraction between oppositely charged ions.

A polar bond is formed by the attraction between oppositely-charged ions.
Atoms that participate in an ionic bond have different electronegativity values from each other.

COVALENT BONDING :

an electron is more attracted to one atom than to another, forming a polar covalent bond.
If the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be nonpolar.

IONIC bonding creates compounds that tend to be relatively strong and hard.
