Which one of the following is incorrect?
An element which has high electro negativity always has high electron gain enthalpy
Electron gain enthalpy is the property of an isolated atom
Electro negativity is the property of a bonded atom
Both electro negativity and electron gain enthalpy are usually directly related to nuclear charge and inversely related to atomic size
If the ionization enthalpy and electron gain enthalpy of an element are 275 Kcal/mole and 86 Kcal mol−1 respectively, then the electro negativity of the element on mulliken scale is
