Final answer:
Group 1 elements are univalent, largely ionic, strong reducing agents, and poor complexing agents.
Step-by-step explanation:
Group 1 elements, also known as alkali metals, are univalent because they have only one valence electron, which they can easily lose to form a univalent cation. They are largely ionic because they readily donate their valence electron to non-metals, forming ionic compounds. These elements are strong reducing agents because they readily give away their valence electron, which has a very low ionization energy. Finally, Group 1 elements are poor complexing agents because they have a relatively small size and low charge, which makes it difficult for them to form stable complexes with other species.
