CHEMISTRY COMMUNITY

In question 14.85, in the 6th edition, it gives a list of metals being Al, Zn, Fe, Co, Ni, Cu, Ag, Au and asks to name the strongest reducing agent starting with the strongest reducing agent. The way I have written it above is the correct answer, however, the solutions manuel does not explain how they came to this conclusion. After reading some posts on chem community, I read that you would determine this by choosing the most negative E value for higher reducing ability and vice versa for oxidizing agents.

Is there any other way to do this? That is, is it possible to determine strength through periodic trends?

The more negative the standard reduction potential, the stronger the metal is as a reducing agent.

The more positive the reduction potential, the more favourable it is to get reduced, and thus, the better oxidising agent it is.
And the same is true vice versa.

The metal is stronger as a reducing agent when the standard potential is more negative and vice versa when the standard potential is more positive, the metal is stronger as an oxidizing agent.
