Concept:A large electronegativity difference between two elements generally results in electron transfer and ionic bonding.
Explanation:When two atoms combine, the difference in their electronegativity values, written as
Δχ, determines the bond type.
If
Δχ is small, the bond is covalent because electrons are shared.
If
Δχ is large, the more electronegative atom pulls electrons almost completely away from the less electronegative atom.
This complete transfer of electrons forms ions, which are held together by electrostatic forces in an ionic compound.
Hence, the product formed in such a case is likely to be ionic.
Answer:D. ionic
