Electronegativity is the property of a bonded atom. The tendency of an atom to attract the shared pair of electrons towards itself is called electronegativity. Different scales of electronegativity have been proposed by different scientists, some of them being Pauling's scale, Mulliken's scale and Allred Rochow scale.
The ionization potential of two atoms A and B are 14 eV/atom and 10.8 eV/atom respectively and their electron affinities are 8.4 eV/atom and 6 eV/atom respectively.
With respect to the above given information answer the following question,
If atoms A and B form a covalent bond, then what is the percent covalent character in the bond? 

Options

A. 19.5
B. 50
C. 80.5
D. 25

Answer
