which pair of ions can form an ionic bond with each other and why?\no cu⁺ and ag⁺; they are both metal ions.\no s²⁻ and o²⁻; they have like charges.\no br⁻ and at⁻; they are both halogen ions.\no li⁺ and br⁻; they have unlike charges.

which pair of ions can form an ionic bond with each other and why?\no cu⁺ and ag⁺; they are both metal ions.\no s²⁻ and o²⁻; they have like charges.\no br⁻ and at⁻; they are both halogen ions.\no li⁺ and br⁻; they have unlike charges.

Answer

Brief Explanations:

Ionic bonds form between ions with opposite charges. Cations (positively - charged ions) and anions (negatively - charged ions) attract each other electrostatically to form an ionic bond. In the given options, only the pair of $Li^{+}$ (cation) and $Br^{-}$ (anion) have unlike charges. Metal - metal ion pairs, like - charged ion pairs, and halogen - halogen ion pairs do not form ionic bonds in the way described.

Answer:

Li⁺ and Br⁻; They have unlike charges.
