Question

An element X has low ionization energy and another element Y has high electron affinity. The bond formed between them could be:

• A. ionic
• B. polar covalent
• C. co-ordinate covalent
• D. non polar covalent

Answer 1

The correct option is A ionic

Ionic bond is formed due to complete transfer of electrons from one element to another element. If one element has low ionization energy than it can easily donate the electrons while other has high electrons affinity then it can easily accept the electrons so its favors ionic bond formation.
