Which one of the following is incorrect ?
\( \mathrm{P} \)
- (1) An element which has high electro negativity
W. always has high electron gain enthalpy
(2) Electron gain enthalpy is the property of an isolated atom
(3) Electronegativity is the property of a bonded atom
(4) Both electronegativity and electron gain enthalpy are usually directly related to nuclear charge and inversely related to atomic size.
