The electronegativity difference between two atoms A and B is `2`, then percentage of covalent character in the molecule is

If the electronegativity difference between two atoms A and B is 2.0, then find out the percentage of covalent character in the molecule.

If the electronegativity difference between two atoms is 2.0, the percentage covalent character of the molecule is :

Difference between atoms and molecules:

The electronegativity values of atoms A and B are 1.8 and 4.0 respectively. The percentage of covalent character of A-B bond is :

For a covalent bond to form between two atoms A and B.
