How does electronegativity differ from electron affinity? Arrange the following in the order of increasing electronegativity: M, M-M .

Ans: Electronegativity and electron affinity differs from each other in the following ways:

ElectronegativityElectron Affinity
  • 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.
  • It is quantative.

According to increasing electronegativity: M- < M < M+
