which pair of ions can form an ionic bond with each other and why?
○ cu⁺ and ag⁺; they are both metal ions.
○ s²⁻ and o²⁻; they have like charges.
○ br⁻ and at⁻; they are both halogen ions.
○ li⁺ and br⁻; they have unlike charges.

Explanation:

Evaluate each option

• Cu⁺ and Ag⁺: Both positive, repel, no bond.
• S²⁻ and O²⁻: Both negative, repel, no bond.
• Br⁻ and At⁻: Both negative, repel, no bond.
• Li⁺ and Br⁻: Positive and negative, attract, form ionic bond.

Answer:

Evaluate each option

• Cu⁺ and Ag⁺: Both positive, repel, no bond.
• S²⁻ and O²⁻: Both negative, repel, no bond.
• Br⁻ and At⁻: Both negative, repel, no bond.
• Li⁺ and Br⁻: Positive and negative, attract, form ionic bond.
