OK: I think I'm on my line right now ......... why is the electrode potential of base metals smaller than that of noble .......... because they form more easily hydrated ones Ions, right? That means that there are more ions on the electrochemical double layer ............ oh, I don't understand ...........

Please help....
That's right, base metals form hydrated ions more easily. Because positive ions go into solution, the metal becomes negatively charged. The less noble the metal, the more ions go into solution and the more the metal is charged negatively (=> more negative redox potential - which you probably mean by "smaller")
Conversely: In the case of noble metals, on the other hand, the tendency to separate is greater, so the metal is positively charged. (=> positive redox potential)

Hope it got clear? Otherwise ask again ...
