Question

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

Explanation:

Ionic bonds form when there is a large difference in electronegativity between two atoms. One atom donates electrons (becoming a cation) and the other accepts electrons (becoming an anion). The electrostatic attraction between these oppositely - charged ions forms the ionic bond. Combustion reactions are reactions with oxygen that release energy. Replacement reactions involve one element replacing another in a compound. Small electronegativity differences are more characteristic of covalent bonds (where electrons are shared).

Answer:

C. large electronegativity differences
