Difference between electron gain enthalphy and electronegativity is described by :

1) Valence electrons

2) Atomic size

3) Atomic radii

3) Atomic number

The statement that "the electronegativity of N on the Pauling scale is 3.0 in all the nitrogen compounds" is incorrect because -

1. Electronegativity of an element is a variable property.

2. Pauling scale is not used to measure electronegativity.

3. The electronegativity of N on the Pauling scale is 12.0

4. None of the above.
