We’re being asked to determine which halogen is the strongest oxidizing agent.
Recall the mnemonics LEO GER.
Loss Electrons → Oxidation → Reducing Agent
Gain Electrons → Reduction → Oxidizing Agent
This means the element that gains electrons/reduced is the oxidizing agent while the element that loses electrons/oxidized is the reducing agent.
The strongest oxidizing agent would be the element that would be easily reduced or easily gains an electron:
Which of the halogens in Table 20.1 is the strongest oxidizing agent?
E) All of the halogens have equal strength as oxidizing agents.
