<h1>The gel-phase selectively adsorbs potassium</h1>
<p>Cells have been shown to selectively adsorb potassium ions over sodium ions (Ling, 1962). The explanation for this might be that potassium (and sodium to a lesser extent) is able to replace the excluded proton. The repelling force between the lattice sheets can be overcome by a stronger attractive force, from an atom with a higher number of protons in the nucleus. Normally, the attractive force falls off rapidly down the rows of the periodic table because of increased distance to the nucleus. But in the ice crystal, the distance of attraction is not limited by the atomic radius, it is limited by the repelling force between the sheets. As long as the atomic radius is less than the repelling force between the sheets, the strength of attraction will continue to increase down the rows as well, explaining the selective adsorption of potassium ions in the cell.</p>
