Verified step by step guidance1
Understand what an oxidizing agent is: an oxidizing agent is a substance that gains electrons in a chemical reaction, causing another substance to be oxidized.
Recall the general properties of the groups listed: Group 1 (Alkali metals) are highly reactive metals that tend to lose electrons, acting as reducing agents rather than oxidizing agents.
Group 2 (Alkaline earth metals) also tend to lose electrons and act as reducing agents, similar to Group 1 but less reactive.
Group 17 (Halogens) are nonmetals that have seven valence electrons and tend to gain one electron to complete their octet, making them strong oxidizing agents.
Group 18 (Noble gases) are mostly inert due to their full valence shell and generally do not act as oxidizing agents under normal conditions.
