Answer

Chlorine in ionic bonding is a nonmetal and tends to gain electrons, meaning that it is reduced. If it is reduced, it is the OXIDIZING AGENT. Potassium in ionic bonding is a metal and tends to lose electrons , so its next electron shell is complete, meaning that is oxidized. If it is oxidized, it is the REDUCING AGENT. Silver has an excess positive charge, meaning that it has tendency to gain electrons in order to become neutral, meaning that is reduced. Therefore, it is oxidizing agent. Notice how zinc has two excess positive charges , therefore it has a tendency to GAIN two electrons to obtain a neutral charge, becoming reduced .Therefore it is the oxidizing agent.
