Question

select the correct answer. which two particles can form an ionic bond with each other? a. a negative oxygen ion and a negative chlorine ion b. a positive sodium ion and a positive magnesium ion c. a positive calcium ion and a negative oxygen ion d. a neutral fluorine atom and a negative sulfur ion

Explanation:

Ionic bonds form between positive (cation) and negative (anion) ions due to electrostatic attraction.

• Option A: Both are negative ions (anions), repel, no bond.
• Option B: Both are positive ions (cations), repel, no bond.
• Option C: Positive calcium ion (cation) and negative oxygen ion (anion) attract, form ionic bond.
• Option D: Neutral atom and negative ion—neutral atom has no strong charge to attract the anion, no ionic bond.

Answer:

C. a positive calcium ion and a negative oxygen ion
