Question

which option describes something that causes ionic bonds to form? (1 point) replacement reactions large electronegativity differences combustion reactions small electronegativity differences

Explanation:

Ionic bonds form when there is a large difference in electronegativity between two atoms. This causes one atom to transfer electrons to the other, creating ions that are attracted to each other. Replacement reactions and combustion reactions are types of chemical reactions but do not directly cause ionic bonds to form. Small electronegativity differences are more characteristic of covalent bonds.

Answer:

large electronegativity differences
