A) low electron affinity, high ionisation energy
B) high electron affinity, low ionisation energy
C) low electron affinity, low ionisation energy
D) high electron affinity, high ionisation energy
Correct Answer: B
Solution :
An ionic bond is formed between an electro- positive metal and a electronegative nonmetal. The electropositive metal converts into a cation, while the electronegative nonmetal converts into a anion. Thus the formation of ionic bond is favoured by (i) Low ionisation potential of metal (ii) Greater value of electron affinity of non-metal (iii) Higher value of lattice energy of the resulting ionic compound.
