The basic difference between the  electron gain enthalpy (Ea) and electronegativity (EN) is:

1. Eis the tendency to lose electrons, while EN is the tendency to repel the shared pairs of electrons.
2. Ea is the tendency to gain neutrons, while EN is the tendency to attract the shared pairs of electrons.
3. Eis the tendency to donate electrons, while EN is the tendency to attract the shared pairs of molecules.
4. Ea is the tendency to gain electrons, while EN is the tendency to attract the shared pairs of electrons.

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.
