Which pair of ions can form an ionic bond with each other and why? a. cu and ag; they are both metal ions. b. s and o; they have like charges. c. br and at; they are both halogen ions. d. li and br; they have unlike charges.

Option (D) is the correct answer.

Explanation:

It is known that opposite or unlike charges attract each other and like charges repel each other.

Therefore, out of the given options only Li and Br has unlike charges. As Li has one positive charge and Br has one negative charge.

Thus, only Li and Br will attract each other as they have unlike charges.
