Question

The most active non metal has:

• A. a high electronegativity
• B. a low electronegativity
• C. a medium electronegativity
• D. large atomic radii
• E. a deliquescent property

Answer 1

The correct option is A a high electronegativity

The most active nonmetal has a high electronegativity.
Non-metals have a tendency to attract a shared pair of electrons in a chemical compound and are electronegative in nature. Fluorine is the most electronegative element. It is a non-metal. Other active non-metals with high electronegativity are $N,O$ and $Cl$.
