The most important conditions for the formation of ionic bond are
Options
- AHigh ionizations energy of the metallic atom and high electron affinity of the non-metallic atom
- BLow ionization of the metallic atom and low electron affinity of the non-metallic atom
- CLow ionization energy of metallic atom and high electron affinity of the non-metallic atom
- 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.
