Detailed Solution

  • Cation is formed by metal & anion is formed  by non-metals. The favorable condition for the formation of an ionic bond is:
  • The low ionization energy and large size of the metal will easily lose electrons to form a cation.
  • High electron affinity and small size of non-metal to form an anion.
    Hence,  Large difference in the electronegativity.
