Question

How electronegativity differs from electron gain enthalpy and ionization enthalpy? ​

Answer 1

SOLUTION

Electronegativity is the tendency of an atom to attract the shared pair of electrons towards it in a covalent bond.  It is the property of atoms in molecules.

Electron gain enthalpy is the tendency of an isolated atom in its gaseous state to accept an additional electron to form a negative ion.  It is the property of isolated atoms.
