Answer 2

Answer:

Na+ and Cl-.

Explanation:

Ionic bonds are the formed by the transfer of electrons to the  electronegative element from the electropositive element. The bonds are held together by the electrostatic force.

The sodium is an electropositive element with one positive charge.Chlorine is an electronegative element with one negative charge. The electrons are transferred from the sodium to the chlorine ions and result in the formation of ionic bonds.

Thus, the correct answer is option (B).
