Differnce and similarity between electron gain enthalpy and electronegativity - Chemistry - Classification of Elements and Periodicity in Properties

Question

Differnce and similarity between electron gain enthalpy and
electronegativity ?

Geetha · Accepted Answer

Electron gain enthalpy
Electronegativity

Its defined as the energy released during the addition of an
electron in the outermost shell
Its expressed in kJ/mole or eV/atom
Its the tendency of an atom to attract the bond pair electron
towards itself Its a mere value That means no unit

Its an isolated property
Its a comparative property

Across the period the value increases and down the group
decreases
Across the period the value increases and down the group
decreases

The first two property is a difference and the last one is the
similarity
