What is an Ionic Character?

Ionic character is a measure of the polarity of a bond. It depends upon the difference in electronegativity of two bonded atoms, more is a difference in electronegativity high will be an ionic character.

Bond between identical atoms:

When a bond is between identical atoms, the electronegativity difference is zero and the ionic character is zero. So the bond is 100% covalent.

Bond between non- identical atoms:

On the other hand bond between dissimilar atoms has some ionic character however there is no 100% ionic bond.

Relationship between electronegativity and percent ionic character:
