We can bring those contours around to the middle of the table. This part of the table shows cations that have some outer-shell electrons and are thus not "hard". If they have a few outer-shell electrons, they're considered "intermediate". From there, they grade to larger and more deformable clouds of outer shell electrons and thus to cations that are considered "soft". The ultimate examples seem to be Au+ and Hg+, which are in looped in the blue contours of lowest ionic potential.

        Continuing with the contours . . . .
