WebFeb 6, 2024 · The ionic radius is half the distance between atomic ions in a crystal lattice. To find the value, ions are treated as if they were hard spheres. The size of an element's ionic radius follows a predictable trend on the periodic table. As you move down a column or group, the ionic radius increases. This is because each row adds a new electron shell.

WebFeb 13, 2024 · Notice as we go further down, the value of $\Delta r$ approaches zero and the actual radius of the ion is also the size of the cavity. This, however, is very much not true for the smaller ions. The Hydrogen ion being an extreme example where a solvation number of 12.0 is obviously unphysical. This, however, does provide a clue for a … WebAn axon with a larger diameter offers less resistance to the movement of ions down the axon, causing ions to move faster down the axon and causing the action potential to be conducted faster. Let me show you the way I think about this by just considering a single sodium ion that's entering an axon through a voltage-gated sodium channel.
