Which option describes something that causes ionic bonds to form?

Question

A. replacement reactions
B. small electronegativity differences
C. combustion reactions
D. large electronegativity differences

Answer 1

D. large electronegativity differences

Ionic bonds typically form between atoms that have a significant difference in electronegativity, usually between metals and nonmetals. The metal atom donates electrons, becoming a positively charged ion, while the nonmetal atom accepts those electrons, becoming a negatively charged ion. This transfer of electrons leads to the formation of ionic bonds.
