Question

Regarding electronegativity, which of the following statements are correct?
i) The element with maximum electronegativity is fluorine.
ii) In Pauling scale, the reference element is silicon.
iii) Elements with stable configuration have high electronegativity.
iv) The element which is most electropositive is hydrogen.

• A. Only (i) correct
• B. Only (ii) correct
• C. Only (iii) correct
• D. Only (iv) is correct

Answer 1

The correct option is A Only (i) correct

1. The most electronegative element is fluorine as it can attract electrons easily.

2. The reference element in the Pauling scale is hydrogen, not silicon.

3. Elements with stable configuration do not posses high electronegativity because it cannot gain electrons.

4. Most electropositive element is francium but is not available much, so we consider caesium not hydrogen.

Option A is correct.
