The most important conditions for the formation of ionic bond are

Options

  1. AHigh ionizations energy of the metallic atom and high electron affinity of the non-metallic atom
  2. BLow ionization of the metallic atom and low electron affinity of the non-metallic atom
  3. CLow ionization energy of metallic atom and high electron affinity of the non-metallic atom
  4. DHigh ionization energy of the metallic atom and high electron affinity of non-metallic atom

Correct answer

C. Low ionization energy of metallic atom and high electron affinity of the non-metallic atom

Step-by-step solution

The most important conditions for the formation of ionic bond are low ionization energy of metallic atom and high electron affinity of the non-metallic atom. Low ionization of the metallic atom and high electron affinity of the non-metallic atom makes the enthalpy of formation of the ionic substance more and more exothermic.
