The electronegativity of the given elements increases in the order

Assertion : Electron affinity refers to an isolated atom's attraction for an additional electron while electronegativity is the ability of an atom of an element to attract electrons towards itself in a shared pair of electrons.
Reason : Electron affinity is a relative number and electronegativity is experimentally measurable.

Going from fluorine to chlorine,bromine and iodine,the electronegativity

Select the incorrect order$(s)$ of electronegativity of the element$(s)$:

If the ionization enthalpy and electron gain enthalpy of an element are $275$ and $86 \ kcal \ mol^{-1}$ respectively,then the electronegativity of the element on the Pauling scale is

The elements $X, Y$ and $Z$ form oxides which are acidic,basic and amphoteric respectively,then the correct order of their electronegativities is
