Question

Consider the above table as periodic table. Then which one will be most electronegative?

• A. A
• B. B
• C. C
• D. D
• E. E

Answer 1

The correct option is D D

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.Halogens are highly electronegative and Fluorine is the most electronegative element.Electronegativity increases across a period because the number of charges on the nucleus increases. That attracts the bonding pair of electrons more strongly while noble gases are most stable as they have completed their octet. Position D occupied is that of halogen group.
