K+ and P3−.

Explanation: Electrostatic attraction occurs between opposite charges. Cs+ and Rb+ are both positive (repel); Cl− and O2− are both negative (repel); Na+ and Ar has a charged ion and a neutral atom (no Coulombic attraction—only weak induced-dipole interactions), so only K+ and P3− show direct ionic attraction.
