Ans: Electronegativity and electron affinity differs from each other in the following ways:
- It is the tendency of an atom of element to attract bond pairs of electrons towards itself.
- It is amount of energy released when an isolated gaseous state atom gain an electron.
- It is applied only to a single atom.
- It is either applied to an atom or a molecule.
- Electronegativity is qualitative.
According to increasing electronegativity: M- < M < M+
