4.17. Electronegativity: Electronegativity is the tendency of an atom to attract shared pair of electrons towards itself. Electronegativity of any given element is never the same.
It depends on the element it is bonded with in a compound. Electronegativity is a relative quantity and cannot be measured.
Whereas, electron gain enthalpy is the change in enthalpy when an electron is added to a neutral gaseous atom to form an anionic specie.It can have a positive or negative value. Every element has a specific electron gain enthalpy value.

The three types of chemical bonds are - ionic, metallic and covalent bonds. When the electrons transfer between the atoms, they form the Ionic bonds by producing charged ions that are attracted to each other. When atoms share electrons, covalent bonds are created. When metal atoms share a sea of delocalized electrons, metallic bonds get created.
