Question

Identify the favourable conditions for the formation of ionic bond.

• A. Low IP value of metal, low EA value of nonmetal
• B. High IP value of metal, high EA value of nonmetal
• C. Low IP value of metal, high EA value of nonmetal
• D. High IP value of metal, low EA value of nonmetal

Answer 1

The correct option is C Low IP value of metal, high EA value of nonmetal

Formation of ionic bond is formed by:

(I) How easily $e^{-}$ can be released from electron positive atom i.e low ionization potential of metal.

(II) How easily electron is accepted by the electro negativity atom i.e. High electron affinity (EA) of non-metal.
