Question

Consider the following statements.
1. IE (I) of nitrogen atom is more than IE(I) of oxygen atom.
2. Electron affinity of oxygen is less than sulphur atom.
3. Electronegativity of an atom has no relation with its ionization enthalpy and electron gain enthaIpy

Which of the above statements are correct?

• A. 1
• B. 1, 2
• C. 2, 3
• D. 1, 2 and 3

Answer 1

Answer: (B)

1, 2

The third is false because the ionization energy can be thought of as a kind of counter property to electronegetivity in the sense that a low ionization energy implies that an element readily gives electrons to a reaction, while a high electronegativity implies that an element strongly seeks to take electrons in a reaction.
