Reduction potential trends on periodic table..help!

[lamborghiniMD]

I'm having trouble keeping these concepts together.

What is the general periodic table trend for reduction potential and oxidation potential?

And Does reduction potential mean reducing agent? Or are reducing agents different? If so, what is the general periodic table trend for reducing agents?

Thanks for the help in advanced!!

Not sure if there is a trend, they'll usually provide reduction potentials in a table for any relevant questions.

Reduction potential = more positive = more likely to be reduced (oxidizing agent)

In short the Reduction potential will follow the Electron Affinity (EA) trend

As you go from left to right and bottom to top, the reduction potential gets more positive.

Ok so lets say on a HYPOTHETICAL MCAT question,
it goes something like this:

Which has the highest reduction potential?
a) Li+
b) Na+
c) K+
d) Rb+

so it would be Li+ right?

Li+ = -3.040
Na+ = -2.713
K+ = -2.925
Rb+= -2.924

Notice that there isn't a linear trend. It would be unreasonable to expect you to be able to answer a question like that.

The question would most likely accompany a passage containing the Ered values. The most educated guess would still be Li though...
