And this interaction creates something known as the Salvation Cage or the Salvation Shell. So essentially, the full positive charge on these potassium ions interacts with the negatively or the partially negative charges on the oxygen atoms of the water molecules. And so the water molecules essentially orient themselves around the potassium to form a cage of water molecules we call the Salvation Cage. And so this Salvation Cage creates an energetically, more stable system and lower in energy because the formation of these bonds essentially releases energy and makes it more stable. And by the same reasoning, we see that if we break the bonds, that actually requires energy. And because two thirds of this internal cavity contains the water, when these potassium ions move into this aqueous environment, they do not lose those salvation cages.
