Opposite pairs form ionic bonds, due to this the answer is D - Li and Br; They have unlike charges.

Answer 2

Answer: 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.
